Chapter Overview
Summary
Psalm 18 (MT) / Psalm 17 (LXX) is the long Davidic thanksgiving parallel to 2 Samuel 22 — a royal song of deliverance with storm-theophany and military-triumph imagery. The closing verse (18:51) — 'great victories to his king … his anointed — to David and his offspring forever' — was read Messianically by early Christians. 18:50 (MT 18:49) is cited at Romans 15:9 as the first of Paul's four-psalm catena for Gentile inclusion.

Structural Notes
MT Ps 18 = LXX Ps 17. 51 verses.

Superscription tying the psalm to David's deliverance from Saul tracks MT. 2 Samuel 22:1 has nearly-identical wording.
I love you, LORD, my strength.
'I love you, LORD, my strength' tracks MT. This opening declaration of love is the only instance in the Psalter of a 'love' (ahav) verb directed toward YHWH.
The LORD is my rock, my fortress, my deliverer, my God, my cliff in whom I take refuge, my shield, the horn of my salvation, my stronghold.
The eight-fold divine-title catalog (rock, fortress, deliverer, God, cliff, shield, horn of salvation, stronghold) tracks MT. Luke 1:69's 'horn of salvation' (keras sōtērias) draws directly on this LXX verse.
I call on the LORD, who is worthy of praise, and I am saved from my enemies.
'I call on the LORD, who is worthy of praise' tracks MT.
The cords of death encompassed me; the torrents of destruction terrified me.
'Cords of death' / 'torrents of destruction' tracks MT. Acts 2:24's 'loosed the pains of death' (lysas tas ōdinas tou thanatou) uses the LXX's ōdines ('pangs') here — the resurrection as escape from death's birth-pangs.
The cords of Sheol surrounded me; the snares of death confronted me.
Cords of Sheol / snares of death tracks MT.
In my distress I called on the LORD; to my God I cried for help. From his temple he heard my voice; my cry reached his ears.

'Rode on a cherub and flew' tracks MT. Ezekiel 1 and Revelation 4 develop the cherub-throne-theophany tradition.
He made darkness his hiding place, his canopy around him — dark waters, thick clouds of the sky.
'Darkness his hiding place' tracks MT.
From the brightness before him his clouds broke through — hail and coals of fire.
Brightness/hail/fire tracks MT.
The LORD thundered from heaven; the Most High gave forth his voice — hail and coals of fire.

Lightning-arrows tracks MT.
Then the channels of the sea were exposed, the foundations of the world laid bare at your rebuke, LORD, at the blast of the breath of your nostrils.
Exposed-sea-channels tracks MT. The image echoes Red-Sea crossing imagery.
He reached down from on high and took hold of me; he drew me out of many waters.

God — the one who arms me with strength and makes my way blameless.
God-arms-with-strength tracks MT.

'Feet like a deer on the heights' tracks MT. Habakkuk 3:19 echoes the same image.

'Ground them fine as dust' tracks MT.

Foreign-submission tracks MT.
Foreigners lose heart and come trembling from their strongholds.
Foreigners-lose-heart tracks MT.

God-vindicator tracks MT.
He rescues me from my enemies. You lift me above my adversaries; from the violent man you deliver me.

Masoretic (WLC)
עַל־כֵּן אוֹדְךָ בַגּוֹיִם יְהוָה וּלְשִׁמְךָ אֲזַמֵּרָה
Therefore I will praise you among the nations, LORD, and sing to your name
Septuagint (LXX)
διὰ τοῦτο ἐξομολογήσομαί σοι ἐν ἔθνεσιν κύριε καὶ τῷ ὀνόματί σου ψαλῶ
Therefore I will confess to you among the Gentiles, O Lord, and to your name I will sing
ROMANS 15:9 CITATION. Paul cites this verse verbatim in its LXX form as the FIRST text in his four-psalm/prophet catena demonstrating the scriptural ground for Gentile inclusion: "as it is written, 'Therefore I will praise you among the Gentiles, and sing to your name.'"
The 'Gentiles' (ethnē) — the same word as 'nations' — supplies Paul's argument that even the Davidic-royal-thanksgiving envisions gentile-praise. The root is 2 Samuel 22:50, which the LXX also preserves.
He gives great victories to his king and shows faithful love to his anointed — to David and his offspring forever.
'His anointed — to David and his offspring forever' tracks MT. The Davidic-covenant perpetuity — a Messianic prophetic-utterance that the NT reads Christologically. Luke 1:69 (Zechariah's Benedictus: 'horn of salvation … in the house of his servant David') echoes this closing.
