The divine reversal

It looks very much as though YHWH in the aftermath of the golden calf incident deliberately reformulates His previous pronouncement. Most striking is the reversal of the order of His attributes. In Exod 34:6, YHWH commences with a fundamental statement about His nature. He is basically merciful and gracious, whereas in the Decalogue the warning of a jealous God precedes YHWH’s attributes of mercy and grace. In other words, there is a radical shift from an emphasis on divine jealousy to an emphasis on divine mercy, grace, and loyalty without denying justice. God allowed Himself in His sovereignty to be persuaded by the persistent prayer of His faithful mediator to overcome justified wrath with grace and loving compassion.—Standing in the Breach, page 92
