He smashed the altar that was at Beit-El and the high place made by Yarov‘am the son of N’vat, who caused Isra’el to sin. Yes, he smashed that altar and the high place; he burned the high place, stamped the ashes to powder, and burned up the asherah.
There is a time and place for everything. Destroying the ungodly things set up in Israel was a righteous act. May we have the zeal and love of Heaven to smash and burn every unholy thing within us, as we sanctify ourselves to our Father.
