1 Samuel 17:49-51 records David's defeat of Goliath, a key example of God equipping him for battle.

1 Samuel 23:5 shows David's victory at Keilah, another instance of God giving him strength in battle.

Psalm 18:32 is the parallel passage, with identical phrasing 'the God who equipped me with strength'.

Psalm 18:39 is a direct parallel, nearly identical to this verse about equipping and sinking enemies.

Psalm 44:5 echoes 'through you we push down our foes' — same theme of victory over enemies.

Psalm 144:2 says God subdues peoples under David — parallel to this verse's 'sink under me'.

Psalm 89:23 repeats God's promise to crush David's adversaries — directly reinforcing that God subdues those who rise against him.
