Albert Barnes Commentary 2 Chronicles 33:7

"And he set the graven image of the idol, which he had made, in the house of God, of which God said to David and to Solomon his son, In this house, and in Jerusalem, which I have chosen out of all the tribes of Israel, will I put my name for ever:" — 2 Chronicles 33:7 (ASV)

The idol—that is, the Asherah (see the note on 2 Kings 21:7), which receives here (and in Ezekiel 8:3, 8:5) the somewhat unusual name of semel. Some regard this as a proper name and compare it with the Greek Σεμέλη Semelē.
