Esau hated his brother Jacob because he had stolen the blessing that was supposed to be his. So he said to himself, “Just as soon as my father dies, I'll kill Jacob.”
David replied, “Tell Joab to cheer up and not to be upset about what happened. You never know who will be killed in a war. Tell him to strengthen his attack against the city and break through its walls.”
and he sent someone to bring in the wise woman who lived in Tekoa. Joab told her, “Put on funeral clothes and don't use any make up. Go to the king and pretend you have spent a long time mourning the death of a loved one.” Then he told her what to say.
David told Joab and everyone with him, “Show your sorrow by tearing your clothes and wearing sackcloth! Walk in front of Abner's body and cry!” David walked behind the stretcher on which Abner's body was being carried.
