'Idolatrous' in the Bible

“The Lord will strike Israel, as a reed is shaken in the water; and He will uproot Israel from this good land which He gave to their fathers, and He will scatter them beyond the [Euphrates] River, because they have made their Asherim, provoking the Lord to anger.

For they also built for themselves high places [to worship idols] and sacred pillars and Asherim [for the goddess Asherah]. These were on every high hill and under every luxuriant tree.

Ahab also made the Asherah. Ahab did more to provoke the Lord God of Israel than all the kings of Israel who were before him.

He walked in all the ways of Asa his father, without turning from them, doing right in the sight of the Lord. However, the high places were not removed; the people still sacrificed and burned incense on the high places.
