Psalms 109

14, 15. Let the iniquity of his fathers be remembered, &c.--Added to the terrible overthrow following his own sin, let there be the imputation of his parents' guilt, that it may now come before God, for His meting out its full consequences, in cutting off the memory of them (that is, the parents) from the earth ( Psalms 34:16 ).

16. Let God remember guilt, because he (the wicked) did not remember mercy.
poor and needy . . . broken in heart--that is, pious sufferer ( Psalms 34:18 , 35:10 , 40:17 ).

17-19. Let his loved sin, cursing, come upon him in punishment ( Psalms 35:8 ), thoroughly fill him as water and oil, permeating to every part of his system (compare Numbers 5:22-27 ), and become a garment and a girdle for a perpetual dress.

20. Let this . . . reward--or, "wages," pay for labor, the fruit of the enemy's wickedness.
from the Lord--as His judicial act.

21, 22. do . . . for me--that is, kindness.
wounded--literally, "pierced" ( Psalms 69:16 Psalms 69:29 ).

23. like the shadow--(Compare Psalms 102:11 ).
tossed up and down--or, "driven" ( Exodus 10:19 ).

24, 25. Taunts and reproaches aggravate his afflicted and feeble state ( Psalms 22:6 Psalms 22:7 ).

26, 27. Let my deliverance glorify Thee (compare Psalms 59:13 ).

28-31. In confidence that God's blessing would come on him, and confusion and shame on his enemies ( Psalms 73:13 ), he ceases to regard their curses, and anticipates a season of joyful and public thanksgiving; for God is near to protect ( Psalms 16:8 , 34:6 ) the poor from all unrighteous judges who may condemn him.
