2 Samuel 17:18
Hushai Warns David to Escape
18 Nevertheless a lad saw them, and told Absalom. But both of them went away quickly and came to a man’s house in Bahurim, who had a well in his court; and they went down into it. 19 Then the woman took and spread a covering over the well’s mouth, and spread ground grain on it; and the thing was not known.20 And when Absalom’s servants came to the woman at the house, they said, “Where are Ahimaaz and Jonathan?”
So the woman said to them, “They have gone over the water brook.”
And when they had searched and could not find them, they returned to Jerusalem.21 Now it came to pass, after they had departed, that they came up out of the well and went and told King David, and said to David, “Arise and cross over the water quickly. For thus has Ahithophel advised against you.” 22 So David and all the people who were with him arose and crossed over the Jordan. By morning light not one of them was left who had not gone over the Jordan.
23 Now when Ahithophel saw that his advice was not followed, he saddled a donkey, and arose and went home to his house, to his city. Then he put his household in order, and hanged himself, and died; and he was buried in his father’s tomb.
24 Then David went to Mahanaim. And Absalom crossed over the Jordan, he and all the men of Israel with him. 25 And Absalom made Amasa captain of the army instead of Joab. This Amasa was the son of a man whose name was Jithra, an Israelite, who had gone in to Abigail the daughter of Nahash, sister of Zeruiah, Joab’s mother. 26 So Israel and Absalom encamped in the land of Gilead.
27 Now it happened, when David had come to Mahanaim, that Shobi the son of Nahash from Rabbah of the people of Ammon, Machir the son of Ammiel from Lo Debar, and Barzillai the Gileadite from Rogelim, 28 brought beds and basins, earthen vessels and wheat, barley and flour, parched grain and beans, lentils and parched seeds, 29 honey and curds, sheep and cheese of the herd, for David and the people who were with him to eat. For they said, “The people are hungry and weary and thirsty in the wilderness.”
