2 Samuel 17:18-29

However, a young man did see them and informed Absalom. So the two left quickly and came to the house of a man in Bahurim. He had a well in his courtyard, and they climbed down into it. Then his wife took the cover, placed it over the mouth of the well, and scattered grain on it so nobody would know anything. Absalom’s servants came to the woman at the house and asked, “Where are Ahimaaz and Jonathan? ” “They passed by toward the water,”  the woman replied to them. The men searched but did not find them, so they returned to Jerusalem. After they had gone, Ahimaaz and Jonathan climbed out of the well and went and informed King David. They told him, “Get up and immediately ford the river, for Ahithophel has given this advice against you.” So David and all the people with him got up and crossed the Jordan. By daybreak, there was no one who had not crossed the Jordan. When Ahithophel realized that his advice had not been followed, he saddled his donkey and set out for his house in his hometown. He set his house in order and hanged himself.  So he died and was buried in his father’s tomb. David had arrived at Mahanaim by the time Absalom crossed the Jordan with all the men of Israel. Now Absalom had appointed Amasa  over the army in Joab’s place. Amasa was the son of a man named Ithra  the Israelite;  , Ithra had married Abigail daughter of Nahash.  Abigail was a sister to Zeruiah, Joab’s mother. And Israel and Absalom camped in the land of Gilead. When David came to Mahanaim, Shobi son of Nahash  from Rabbah  of the Ammonites, Machir son of Ammiel from Lo-debar,  and Barzillai the Gileadite from Rogelim  brought beds, basins,  and pottery items. They also brought wheat, barley, flour, roasted grain, beans, lentils,  honey, curds, sheep, goats, and cheese  from the herd for David and the people with him to eat. They had reasoned, “The people must be hungry, exhausted, and thirsty in the wilderness.”
