Four Hebrew words are translated 'brook.'

1. aphiq, Psalm 42:1 : water held in by banks, translated also 'channel.'

2. yeor , Isaiah 19:6-8 , a river, canal, fosse: applied to the Nile in Exodus 1:22 , etc.

3. mikal, 2 Samuel 17:20 , a small brook.

4. nachal, Genesis 32:23 , etc., a mountain torrent often dry in summer, and thus often disappointing, as in Job 6:15 . Such are numerous in Palestine. (This is the word in all the passages where 'brook' occurs in the O.T. except those above enumerated.) The same is called in the N.T. χείμαρρος, 'winter flowing.' John 18:1 . Its Eastern name is wady.
