Acts 1 opens with Luke's prologue addressing Theophilus, connecting this volume to the Gospel of Luke. The risen Jesus instructs his apostles to wait in Jerusalem for the promise of the Holy Spirit. After forty days of post-resurrection appearances, Jesus ascends into heaven from the Mount of Olives. The apostles return to Jerusalem and devote themselves to prayer. The chapter closes with the selection of Matthias to replace Judas Iscariot, restoring the Twelve.
What Makes This Chapter Remarkable
Luke explicitly frames Acts as a sequel — 'the first account' (ton proton logon) refers to his Gospel. The forty-day period of post-resurrection teaching echoes Israel's forty years in the wilderness and Moses' forty days on Sinai. The ascension narrative is remarkably restrained — no dramatic special effects, just Jesus 'lifted up' and a cloud receiving him. The 'two men in white' echo the angelic figures at the empty tomb (Luke 24:4). The lot-casting for Matthias is the last recorded instance of this Old Testament decision-making method; after Pentecost, the Spirit replaces the lot.
Translation Friction
The Greek phrase 'baptized with the Holy Spirit' (baptisthesesthe en pneumati hagio) in verse 5 creates the theological foundation for the Pentecost narrative in chapter 2. The question about restoring the kingdom to Israel (v. 6) reveals the disciples' persistent expectation of a political Messiah, which Jesus redirects without directly denying. The criteria for Judas's replacement (vv. 21-22) — someone present from John's baptism through the ascension — defines apostolic witness as eyewitness testimony.
Connections
The prologue connects to Luke 1:1-4. The promise of the Spirit connects to Joel 2:28-32 (quoted in Acts 2). The ascension connects to Daniel 7:13-14 (the Son of Man coming with clouds). The replacement of Judas fulfills the Psalms citations in verses 16 and 20 (Psalm 69:25 and Psalm 109:8). The number twelve connects to the twelve tribes of Israel, maintaining the symbolic completeness of the apostolic body.
Here used in the literary sense of a written composition or account. The same word carries immense theological weight in John 1:1, but here it functions simply as a reference to Luke's prior work.
Translator Notes
The Greek ton proton logon ('the first account/word') refers to Luke's Gospel. The verb epoiesameen ('I made/composed') is a standard literary term for writing a work. 'Theophilus' means 'lover of God' or 'friend of God' — whether this is a real person or a symbolic addressee is debated, though the honorific 'most excellent' used in Luke 1:3 suggests a real patron.
The phrase 'began to do and to teach' (eerxato poiein te kai didaskein) implies that what Jesus 'began' in the Gospel continues through his apostles in Acts — the ascension does not end Jesus's work but changes its mode.
Until the day in which he was taken up, following that he by way of the Holy Ghost had given commandments to the apostles whom he had chosen:.

Notes & Key Terms
Translator Notes
The verb aneleemphthee ('was taken up') is the technical term for the ascension, used again in verse 11 and in 1 Timothy 3:16. The phrase 'through the Holy Spirit' (dia pneumatos hagiou) can modify either 'given instructions' or 'chosen' — the ambiguity is present in the Greek. We follow the more natural reading linking it to the instructions.
The word apostolois ('apostles') here designates the specific group Jesus chose, not the broader later usage of the term. Luke uses it as a technical title for the Twelve.
He also presented himself alive to them after his suffering, with many convincing proofs, appearing to them over a period of forty days and speaking about the kingdom of God.

The Greek tekmeriois ('proofs, convincing evidence') is a strong term from legal and philosophical discourse — these are not casual sightings but demonstrable evidence. Luke the historian emphasizes the evidentiary quality of the resurrection appearances.
The forty-day period (di' heemerōn tesserakonta) is mentioned only here in the New Testament. It echoes Moses' forty days on Sinai (Exodus 24:18) and Elijah's forty-day journey to Horeb (1 Kings 19:8). The risen Jesus uses this time to teach about the kingdom — a post-resurrection seminar on God's reign.

The Greek synalizomenos is debated: it may mean 'eating together with' (from hals, 'salt') or 'being assembled with' (from syn + halizō). The eating interpretation is favored by many scholars as it emphasizes the physical reality of the risen Jesus sharing meals with his disciples (cf. Luke 24:41-43). We follow this reading.
The 'promise of the Father' (teen epangelian tou patros) refers to the Holy Spirit, as clarified in verse 5. This connects to Joel 2:28-29 and Jesus's own promises in Luke 24:49 and John 14-16.

βαπτίζωbaptizō
"baptized"—to dip, immerse, wash, baptize
The root meaning is immersion or dipping. The metaphorical extension to Spirit-baptism suggests being overwhelmed or immersed in the Spirit's presence and power.
Translator Notes
The contrast between John's water baptism and the coming Spirit baptism is a key theme in Luke-Acts (cf. Luke 3:16). The preposition en can mean 'with' or 'in' — 'baptized in the Holy Spirit' and 'baptized with the Holy Spirit' are both valid renderings. We choose 'with' for clarity, though the immersion imagery of 'in' captures the Greek metaphor better.
The phrase 'not many days from now' (ou meta pollas tautas heemeras) deliberately avoids specifying the exact timing, building anticipation for the Pentecost event in chapter 2.

The imperfect tense eerōtōn ('they were asking, kept asking') suggests persistent questioning, not a single query. The verb apokathistaneis ('are you restoring') carries overtones of the prophetic hope for Israel's restoration (cf. Malachi 4:5-6, where Elijah 'restores' all things). The disciples assume the Spirit's coming means political restoration — Jesus redirects but does not deny the eventual restoration of Israel.

Jesus distinguishes two temporal concepts: chronous ('times,' referring to duration or chronological periods) and kairous ('seasons,' referring to appointed moments or decisive occasions). Together they cover both the timeline and the turning points of God's plan. The Father alone holds authority (exousia) over these — this is a boundary on human knowledge, not a denial that restoration will occur.

μάρτυςmartys
"witnesses"—witness, one who testifies, martyr
The term carries legal weight — a witness testifies to what they have personally seen and heard. The later development into 'martyr' reflects the reality that faithful testimony often led to death.
δύναμιςdynamis
"power"—power, ability, might, miracle, force
Not political or military power, but the enabling power of God's Spirit for the task of witness. This redefines the 'power' the disciples expected in verse 6.
Translator Notes
This verse serves as the programmatic outline for the entire book of Acts: Jerusalem (chapters 1-7), Judea and Samaria (chapters 8-12), and to the ends of the earth (chapters 13-28). The Greek dynamin ('power') is the root of English 'dynamite' — the Spirit's power is not passive but active and transformative.
The word martyres ('witnesses') is the root of English 'martyr.' In Acts, bearing witness will cost some disciples their lives (Stephen in chapter 7, James in chapter 12). Witness and suffering are linguistically and theologically intertwined.
The phrase 'ends of the earth' (eschatou tees gees) echoes Isaiah 49:6, where the Servant of the LORD is 'a light for the nations, that my salvation may reach to the end of the earth.' Jesus's commission fulfills the Isaianic servant vision.

The ascension is described with remarkable restraint. The passive epeerthee ('was lifted up') indicates divine action — Jesus does not fly away under his own power but is taken up by God. The cloud (nephelee) echoes the cloud of divine presence throughout the Old Testament: the pillar of cloud in the wilderness (Exodus 13:21), the cloud on Sinai (Exodus 24:15-18), the cloud filling the temple (1 Kings 8:10-11), and the Son of Man coming with clouds (Daniel 7:13).

The verb atenizontes ('staring intently, gazing fixedly') conveys the disciples' stunned focus — they cannot look away. The 'two men in white' (andres duo en esthesesin leukais) parallels the two figures at the empty tomb in Luke 24:4. Luke identifies them as men rather than angels, though their white clothing signals heavenly origin. Two witnesses fulfill the Deuteronomic requirement for valid testimony (Deuteronomy 19:15).

The address 'Men of Galilee' (andres Galilaioi) identifies the apostles by their regional origin and echoes the pattern of address used throughout Acts (cf. 'Men of Israel,' 'Men of Athens'). The promise of return 'in the same way' (hon tropon) — visibly, bodily, with clouds — becomes the foundation of the Christian hope of the second coming. The threefold repetition of 'heaven' (ouranos) in this verse emphasizes both Jesus's destination and the direction from which he will return.

A 'Sabbath day's journey' (sabbatou echon hodon) was approximately 2,000 cubits or about half a mile (roughly 1 kilometer), the maximum distance one could travel on the Sabbath according to rabbinic tradition. Luke's geographical note serves both literary and practical purposes — the Mount of Olives is close enough that the disciples could quickly obey Jesus's command to stay in Jerusalem.
The Mount of Olives (Elaiōnos, 'of olives') was associated with eschatological expectation in Zechariah 14:4, where the LORD's feet stand on the Mount of Olives at the final redemption.

The 'upper room' (to hyperōon) was likely a large second-story room in a Jerusalem house, possibly the same location as the Last Supper (Luke 22:12). The list of eleven apostles differs in order from Luke 6:14-16 — notably Peter and John are paired here (as they will be partners throughout Acts 1-8), whereas in Luke's Gospel Peter and Andrew are paired as brothers. Simon 'the Zealot' (ho zeelotees) may indicate former membership in the Zealot political movement or simply intense religious zeal.
'Judas son of James' (Ioudas Iakōbou) — the KJV renders this 'brother of James,' but the Greek more naturally reads 'son of.' This is the same figure called Thaddaeus in Matthew 10:3.

The Greek proskarterountes ('devoting themselves, persisting, being steadfast in') is a strong word indicating persistent, wholehearted commitment — not casual prayer meetings but intense, unified intercession. The adverb homothymadon ('with one mind, unanimously') is a favorite word of Luke in Acts, appearing ten times to describe the early church's unity.
This is Mary's last appearance in the New Testament. She is mentioned among the community of prayer, not elevated above it. The 'brothers' (adelphois) of Jesus are mentioned — the same brothers who did not believe during his ministry (John 7:5) are now part of the believing community. James the brother of Jesus will emerge as a leader of the Jerusalem church (Acts 15, 21).

The Greek adelphōn ('brothers') is used inclusively here, as the context clearly includes women (v. 14). We render 'brothers and sisters' to reflect the inclusive usage. The number 120 may be symbolically significant — Jewish tradition required a minimum of 120 men to establish a local council (sanhedrin), so the community meets the threshold for self-governance.
The phrase ochlos onomatōn ('a crowd of names') is an unusual expression; 'names' (onomatōn) here means 'persons' — a Semitic idiom reflected in the Greek.

This parenthetical note (vv. 18-19) is Luke's aside to the reader, not part of Peter's speech. The account of Judas's death differs from Matthew 27:3-10, where Judas hangs himself and the priests buy the field. Various harmonizations have been proposed, but the texts present genuinely different traditions. We render the Greek as given without attempting to reconcile.
The Greek preeness genomenos ('falling headfirst/prone') and elakēsen mesos ('burst open in the middle') is graphic and visceral. Luke does not sanitize the scene. The 'reward of wickedness' (misthou tees adikias) echoes the language of Balaam's wages in 2 Peter 2:15.

Luke translates the Aramaic name for his Greek-speaking audience. Hakeldamach (Ἁκελδαμάχ) represents the Aramaic chaqel dema ('field of blood').

Peter quotes two Psalms: Psalm 69:25 (LXX 68:26) and Psalm 109:8 (LXX 108:8). The first applies to Judas's vacated place; the second provides the scriptural basis for selecting a replacement. The Greek episkopeen ('position of oversight, office') is the root of 'bishop/episcopate' — the KJV's 'bishopric' is a translation that reads later church structure back into the text.

The timeframe spans from John's baptism (the beginning of Jesus's public ministry) to the ascension.

Joseph Barsabbas bears three names: his given name Joseph, his Aramaic patronymic Barsabbas ('son of the Sabbath' or 'son of the elder'), and his Latin cognomen Justus ('the righteous one').

The title kardiognōsta ('knower of hearts') appears only here and in Acts 15:8 in the New Testament. It is ambiguous whether the prayer is addressed to God the Father or to the risen Jesus — 'Lord' (kyrie) can refer to either in Acts. The verb exelexō ('you have chosen') is aorist, implying that God has already made the selection; the lot merely reveals the divine choice.

The phrase 'his own place' (ton topon ton idion) is a grim euphemism for Judas's fate after death. The verb parebee ('turned aside, transgressed') suggests a deliberate departure from the path — Judas did not merely fall but actively deviated.
