And thus said Shimei, when he cursed, come out, come out
Or rather, "go out, go out" F20; that is, out of the nation, where he deserved not to live, as he judged, and out of the kingdom, which he had usurped, as he supposed; and the repeating the words not only denotes his vehement desire to have him gone, but the haste he should make to get out, or he was liable to be overtaken by Absalom and his forces; upbraiding him also with the hurry he was in, and the speedy flight he was making:
thou bloody man, and thou man of Belial;
or wicked man; perhaps referring by these characters in the one to the murder of Uriah, and in the other to his adultery with Bathsheba; and these crimes coming fresh into David's mind hereby, might make him more mild and humble under his reproaches.
