Now they began the consecration on the first day of the first month, and on the eighth day of the month they entered the porch of the Lord. Then they consecrated the house of the Lord in eight days, and finished on the sixteenth day of the first month.

For in the eighth year of his reign while he was still a youth, he began to seek the God of his father David; and in the twelfth year he began to purge Judah and Jerusalem of the high places, the Asherim, the carved images and the molten images.
