'Brook' in the Bible

All the country wept with a loud voice, and all the people passed over: the king also himself passed over the brook Kidron, and all the people passed over, toward the way of the wilderness.

Absalom's servants came to the woman to the house; and they said, "Where are Ahimaaz and Jonathan?" The woman said to them, "They have gone over the brook of water." When they had sought and could not find them, they returned to Jerusalem.
