Psalms 107-110 – Can we pray imprecatory (curses against enemies) prayers like David’s?

Job 17:9 “Nevertheless the righteous shall hold to his way, And he who has clean hands shall grow stronger and stronger.

Psalm 51:7-17 Purify me with hyssop, and I shall be clean; Wash me, and I shall be whiter than snow. 8Make me to hear joy and gladness, Let the bones which Thou hast broken rejoice. 9Hide Thy face from my sins, And blot out all my iniquities. 10Create in me a clean heart, O God, And renew a steadfast spirit within me. 11Do not cast me away from Thy presence, And do not take Thy Holy Spirit from me. 12Restore to me the joy of Thy salvation, And sustain me with a willing spirit. 13Then I will teach transgressors Thy ways, And sinners will be converted to Thee. 14Deliver me from bloodguiltiness, O God, Thou God of my salvation; Then my tongue will joyfully sing of Thy righteousness. 15O Lord, open my lips, That my mouth may declare Thy praise. 16For Thou dost not delight in sacrifice, otherwise I would give it; Thou art not pleased with burnt offering. 17The sacrifices of God are a broken spirit; A broken and a contrite heart, O God, Thou wilt not despise.

Isa. 29:19 The afflicted also shall increase their gladness in the LORD, And the needy of mankind shall rejoice in the Holy One of Israel.

Mal. 3:3 “And He will sit as a smelter and purifier of silver, and He will purify the sons of Levi and refine them like gold and silver, so that they may present to the LORD offerings in righteousness.
