We read in 2 Samuel 20:11–22 that Joab took command as though nothing had happened. The troops were stopping in the road to gawk at Amasa’s corpse. So heartless Joab dragged Amasa’s body to a field and threw a garment over him, without bothering to bury him. Joab marched as far north as Abel Beth Maacah (four miles west of Dan and north of the Sea of Kinnereth) through the territory of the Berites (site unknown) to summon reinforcements.
Joab found Sheba safely hidden behind the city wall, apparently prepared to face a long siege. While attempting to batter down the walls Joab was contacted by a wise woman from the city who yelled over the wall that she wanted to talk with him. She told Joab of her own fame as a purveyor of wisdom (2 Samuel 20:18) and then asked why he was destroying her city which had always been loyal to Israel. The city, as a mother in Israel, was a prominent one.
To this Joab replied that he was not attacking the city itself but only wanted Sheba, the rebel who had presumed to lead Israel away from its king. If she would assist in delivering Sheba over to him, he would end his siege. Soon the head of Sheba was thrown over the wall to Joab. Successful in his mission, Joab stopped the siege and returned to Jerusalem.
