The righteous shall rejoice when he seeth the vengeance: he shall wash his feet in the blood of the wicked.
Ver. 10. The righteous shall rejoice, &c.] Giving God the glory of his justice against his enemies and care of his poor people. See Exodus 15:1,27 : 1Ki 15:3 Esther 7:10; Est 8:9 Proverbs 11:10 .
He shall wash his feet in the blood of the wicked] A speech borrowed from great conquerors, wading up to the ancles in the blood of their enemies; or, as some think, from those that tread the wine-press with joy. Some make this the sense: the righteous, seeing the ruin of the wicked, shall become more cautious; according to that, Alterius perditio tua sit cautio.
