2 Samuel 17:22

18But a boy saw them, and told Absalom. Then they both went away quickly and came to the house of a man in Bahurim, who had a well in his court; and they went down there.

19The woman took and spread the covering over the well’s mouth, and spread out crushed grain on it; and nothing was known.

20Absalom’s servants came to the woman to the house; and they said, “Where are Ahimaaz and Jonathan?” The woman said to them, “They have gone over the brook of water.” When they had sought and could not find them, they returned to Jerusalem.

21After they had departed, they came up out of the well and went and told King David; and they said to David, “Arise and pass quickly over the water; for thus has Ahithophel counseled against you.”

22Then David arose, and all the people who were with him, and they passed over the Jordan. By the morning light there lacked not one of them who had not gone over the Jordan.

23When Ahithophel saw that his counsel was not followed, he saddled his donkey, arose, and went home to his city, set his house in order, and hanged himself; and he died, and was buried in the tomb of his father.

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

25Absalom set Amasa over the army instead 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 to Zeruiah, Joab’s mother.

26Israel and Absalom encamped in the land of Gilead.
