Psalm 51:1 also pleads for mercy, but for forgiveness of sin, while Psalm 30:10 asks for help in distress — both cry for divine mercy.

Psalm 54:4 declares 'God is my helper' — the exact role David asks for in Psalm 30:10, showing God's faithfulness.

Psalm 143:1 echoes the same opening plea — 'Hear, O LORD' and cry for mercy — reinforcing the pattern of David's desperate prayer.

Psalm 28:7 declares God as helper and strength — the same role David pleads for in Psalm 30:10, showing the confidence that follows answered prayer.
