2 Samuel 17:17-20

17Now Jonathan and Ahimaaz were staying by En-rogel; and a maid-servant used to go and tell them; and they went and told king David: for they might not be seen to come into the city. 18But a lad saw them, and told Absalom: and they went both of them away quickly, and came to the house of a man in Bahurim, who had a well in his court; and they went down thither. 19And the woman took and spread the covering over the well’s mouth, and strewed bruised grain thereon; and nothing was known. 20And Absalom’s servants came to the woman to the house; and they said, Where are Ahimaaz and Jonathan? And the woman said unto them, They are gone over the brook of water. And when they had sought and could not find them, they returned to Jerusalem.
