Psalms 64:8
Ver. 8. So shall they make their own tongue to fall upon themselves,.... The evil things they have wished for, threatened unto, and imprecated on others, shall come upon themselves; the curses they have cursed others with shall come upon themselves; the pit they have dug for others, they fall into. So Haman, to whom some apply the psalm, was hanged on the gallows he made for Mordecai; and the accusers of Daniel, to whom others apply it, were cast into the same den of lions they procured for him; and Babylon, who has been drunk with the blood of the saints, shall have blood given her to drink.
all that see them shall flee away; not being able to help them, nor to bear the horrible sight, and fearing the same judgments should fall on themselves; see Nu 16:34. Or, "they shall move themselves" {d}; shake their heads in a way of derision, as Jarchi interprets it; or skip for joy, as the word is rendered in Jer 48:27; and then it must be understood of the righteous; who, seeing the vengeance on the wicked, rejoice, as in Ps 52:6; though, as they are afterwards particularly mentioned, others seem to be designed. The word is used for lamenting and bemoaning one's self, in Jer 31:18; and so may be applied to the friends of the wicked lamenting and bemoaning their ruin, and their being bereaved of them, Re 18:9.
