'Brook' in the Bible

And he took his staff in his hand, and chose him five smooth stones out of the brook, and put them in the shepherd's bag which he had, even in his wallet; and his sling was in his hand: and he drew near to the Philistine.

So David went, he and the six hundred men that were with him, and came to the brook Besor, where those that were left behind stayed.

But David pursued, he and four hundred men; for two hundred stayed behind, who were so faint that they could not go over the brook Besor.

And David came to the two hundred men, who were so faint that they could not follow David, whom also they had made to abide at the brook Besor; and they went forth to meet David, and to meet the people that were with him: and when David came near to the people, he saluted them.
