Psalm 18:3 is the identical verse, mirroring David's song of deliverance word for word.

Psalm 50:15 explicitly promises deliverance to those who call on God in trouble, the same principle David declares here.

Psalm 55:16 uses nearly identical phrasing: 'I call to God, and the Lord will save me' — a strong parallel of confident prayer for salvation.

Psalm 57:1-3 expands the theme: taking refuge, crying to God Most High, and receiving salvation from heaven against pursuers.

Psalm 34:6 echoes this cry of a poor man who called and was saved — reinforcing that God hears and delivers those who call on Him.

Psalm 56:9 adds that enemies turn back when David calls — specifying the outcome of his cry for deliverance.

Romans 10:13 applies the same 'call on the Lord and be saved' principle to salvation in Christ, universalizing David's experience.

Revelation 4:11 grounds God's worthiness in his act of creation, expanding the basis for praise.

Revelation 5:12 ascribes worthiness to the Lamb, a new covenant application of the praise theme.
