They trespassed against the God of their fathers, and played the prostitute after the gods of the peoples of the land, whom God destroyed before them.
1 Chronicles 5:18-22 record an important victory over their enemies by the trans-Jordanic tribes, no record of which is found elsewhere in the Bible. This should warn us against assuming that the Bible records any such thing as a complete history of God's people.  "There may be many other gaps in Samuel and Kings which Chronicles does not fill."[5]
