1 Chronicles 5:19-20

19And these Israelites, [on the east side of the Jordan River] made war with the Hagrites [a tribe of northern Arabia], Jetur, Naphish, and Nodab.

20They were given help against them, and the Hagrites were handed over to them, and all who were allied with them; for they cried out to God [for help] in the battle; and He granted their entreaty because they relied on and trusted in Him.
