Why are the gods condemned in Psalm 82?

This is the difference between Yahweh and the gods who stand accused in Psalm 82. These gods fail to uphold justice (Ps 82:2–4), not because they are evil and want to encourage injustice—ancient Near Eastern kings testify that their gods demanded justice—but because they are codependent; if they punish their people as they should, they will no longer receive sacrifices to meet their needs (compare the sentiment expressed in Jer 7:9–10). In contrast, Yahweh’s relationship with his people is not defined by codependence but justice.— The Lost World of the Israelite Conquest, 123–24
