'Brook' in the Bible

While all the country was weeping with a loud voice, all the people crossed over. The king also crossed the Brook Kidron, and all the people went on toward the way of the wilderness [that lies between Jerusalem and the Jordan River].

Then Absalom’s servants came to the woman at the house and asked, “Where are Ahimaaz and Jonathan?” And the woman said to them, “They have crossed over the brook.” When they searched and could not find them, they returned to Jerusalem.
