2 Kings 21:7

And he set a graven image of the grove that he had made in the house, of which the LORD said to David, and to Solomon his son, In this house, and in Jerusalem, which I have chosen out of all tribes of Israel, will I put my name for ever:

And he set a graven image, х pecel (H6459) haa-'Asheeraah (H842)] - a carved image of the Asherah, a statue or relieve figure. The placing of the Asherah within the precincts of the temple, which was dedicated to the worship of the true God, is dwelt upon as the most aggravated outrage of the royal idolater.
