Then David got up from the floor, washed and anointed himself, and changed his clothes. Then he went to the House of Adonai and worshipped. When he came back to his own palace, he asked for food, so they set food before him and he ate.
So Joab sent word to Tekoa and brought a wise woman from there. He said to her, “Please pretend to be a mourner and put on mourning clothes. Do not anoint yourself with oil but be like a woman who has been mourning many days for the dead.
So bathe and perfume yourself, put on your cloak and go down to the threshing floor. But do not make yourself known to the man until he has finished eating and drinking.
