Esau hated Jacob because of the blessing with which his father blessed him. Esau said in his heart, “The days of mourning for my father are at hand. Then I will kill my brother Jacob.”
They came to the threshing floor of Atad, which is beyond the Jordan, and there they lamented with a very great and severe lamentation. He mourned for his father seven days.
Then David said to the messenger, “Tell Joab, ‘Don’t let this thing displease you, for the sword devours one as well as another. Make your battle stronger against the city, and overthrow it.’ Encourage him.”
Joab sent to Tekoa and brought a wise woman from there, and said to her, “Please act like a mourner, and put on mourning clothing, please, and don’t anoint yourself with oil; but be as a woman who has mourned a long time for the dead.
David said to Joab and to all the people who were with him, “Tear your clothes, and clothe yourselves with sackcloth, and mourn in front of Abner.” King David followed the bier.
