'Brook' in the Bible

So Solomon observed the feast at that time for seven days, and all Israel with him, a very great assembly who came from the entrance of Hamath to the brook of Egypt.

He also removed Maacah, the mother of King Asa, from the position of queen mother, because she had made a horrid image as an Asherah, and Asa cut down her horrid image, crushed it and burned it at the brook Kidron.

They arose and removed the altars which were in Jerusalem; they also removed all the incense altars and cast them into the brook Kidron.
