2 Chronicles 28:23

For he sacrificed unto the gods of Damascus, which smote him: and he said, Because the gods of the kings of Syria help them, therefore will I sacrifice to them, that they may help me. But they were the ruin of him, and of all Israel.

For he sacrificed unto the gods of Damascus. His superstitious mind led him to believe that he would, by doing them homage, obtain some share of the favours they had bestowed on the Syrians.
