" The Lord God, through Moses, forbade the worship of Asherah. The Law specified that a grove of trees was not to be near the altar of the Lord (Deuteronomy 16:21). Despite God’s clear instructions, Asherah-worship was a perennial problem in Israel. As Solomon slipped into idolatry, one of the pagan deities he brought into the kingdom was Asherah, called “the goddess of the Sidonians” (1 Kings 11:5, 33). Later, Jezebel made Asherah-worship even more prevalent, with 400 prophets of Asherah on the royal payroll (1 Kings 18:19). At times, Israel experienced revival, and notable crusades against Asherah-worship were led by Gideon (Judges 6:25-30), King Asa (1 Kings 15:13), and King Josiah (2 Kings 23:1-7)."
There is a long history of heresy in Judaism and Christianity. Some heresies become practice depending upon popularity and hierarchy of believers.
