Israel’s Harlotry and Idolatry

 Explain Ezekiel 23:20, a friend asks - 

It’s a metaphor for Israel’s repeated harlotry with the foreign nations and their false gods, turning away from Yahweh their true husband toward other lovers in idolatry. And what is true on a national or corporate level metaphorically - adultery - is true on an individual level, as shown from the golden calf incident at Sinai on forward throughout Old Covenant Israel’s history.
