2 Samuel 17:23-26 New American Standard Bible (NASB)

23. Now when Ahithophel saw that his counsel was not followed, he saddled his donkey and arose and went to his home, to his city, and set his house in order, and strangled himself; thus he died and was buried in the grave of his father.

24. Then David came to Mahanaim. And Absalom crossed the Jordan, he and all the men of Israel with him.

25. Absalom set Amasa over the army in place of Joab. Now Amasa was the son of a man whose name was Ithra the Israelite, who went in to Abigail the daughter of Nahash, sister of Zeruiah, Joab's mother.

26. And Israel and Absalom camped in the land of Gilead.
