1 Chronicles 5:20

And they were helped against them, the Lord Himself taking their part, and the Hagarites were delivered into their hand, and all that were with them, probably in return for raids which had been made by the desert nomads; for they cried to God in the battle, and He was intreated of them, because they put their trust in Him, for these events took place while the tribes of the country east of Jordan were still faithful to the Lord.
