Because Manasseh king of Judah hath done these abominations, and hath done wickedly above all that the Amorites did, which were before him, and hath made Judah also to sin with his idols:
Because Manasseh, the king of Judah, did these terrible things and was even worse than the people who lived there before him, the Amorites. He also caused Judah to follow his idols and sin.
