Context Reading
1Manasseh was twelve years old when he began to reign, and he reigned fifty and five years in Jerusalem: 2But did that which was evil in the sight of the LORD, like unto the abominations of the heathen, whom the LORD had cast out before the children of Israel. 3For he built again the high places which Hezekiah his father had broken down, and he reared up altars for Baalim, and made groves, and worshipped all the host of heaven, and served them.
