1 Kings 16:33

And Ahab made a grove
About the temple of Baal, or elsewhere, in which he placed an idol, and where all manner of filthiness was secretly committed; or rather "Asherah", rendered "grove", is Astarte, the goddess of the Zidonians, an image of which Ahab made:

and Ahab did more to provoke the Lord God of Israel to anger than all
the kings of Israel that were before him:
his idolatries being more open and barefaced, and without any excuse, presence, or colour, as well as more numerous.
