So David arose from the ground, washed, anointed himself, and changed his garments. Then he entered the house of the Lord and worshipped. He then went in to his own house. When he asked, they set down food for him and ate.
So Joab sent a request to Tekoa and brought from there a wise woman. He instructed her, “Act as if you are observing mourning rites. Put on mourning garments, and do not anoint yourself with oil, but act like a woman who has been mourning over the dead like this for many days.
Now wash and anoint yourself, and put on your best clothes. Then go down to the threshing floor, but do not let the man know you are there until he has finished eating and drinking.
