2 Samuel 17:17-22

17Now Jonathan and Ahimaaz were staying at En-rogel, where a servant girl would come and pass along information to them. They in turn would go and inform King David, for they dared not be seen entering the city. 18But a young man did see them and told 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. 19Then the man’s wife took a covering, spread it over the mouth of the well, and scattered grain over it so nobody would know a thing.

20When Absalom’s servants came to the woman at the house, they asked, “Where are Ahimaaz and Jonathan?”

“They have crossed over the brook,” she replied. The men searched but did not find them, so they returned to Jerusalem.

21After the men had gone, Ahimaaz and Jonathan climbed up out of the well and went to inform King David, saying, “Get up and cross over the river at once, for Ahithophel has given this advice against you.”

22So David and all the people with him got up and crossed the Jordan. By daybreak, there was no one left who had not crossed the Jordan.
