And the LORD was greatly enough incensed with Aaron to destroy him, and I (Moses) interceded on behalf of Aaron, too, at that time. And your offense that you made, the calf, I had taken and burned it in the fire and crushed it, grinding it well…Only after Moses destroyed the golden calf did God become incensed with Aaron for his role in this episode. When Moses stood up to the people, he demonstrated that it was possible to resist them. At that moment, explains Malbim, Aaron’s explanations looked like a feeble excuse. Feeling responsible for making his brother look bad, Moses felt doubly responsible to save him: and I (Moses) interceded on behalf of Aaron, too, at that time.
