So David got up from the ground, washed, anointed himself, and changed his clothes; and he went into the house of the Lord and worshiped. Then he went to his own house, and when he asked, they served him food, and he ate.
So Joab sent a messenger to Tekoa and brought a wise woman from there, and said to her, “Please follow mourning rites, and put on mourning garments now, and do not anoint yourself with oil but be like a woman who has been mourning for the dead for many days.
Wash yourself therefore, and anoint yourself, and put on your best clothes, and go down to the threshing floor; but do not reveal yourself to the man until he has finished eating and drinking.
