tn The expression “make proclamation in the name of Yahweh” (here a perfect tense with vav [ו] consecutive for future) means to declare, reveal, or otherwise make proclamation of who Yahweh is. The “name of Yahweh” (rendered “the name of the Lord” throughout) refers to his divine attributes revealed to his people, either in word or deed. What will be focused on first will be his grace and compassion.

sn God declares his mercy and grace in similar terms to his earlier self-revelation (“I am that I am”): “I will be gracious to whom I will be gracious.” In other words, the grace and mercy of God are bound up in his own will. Obviously, in this passage the recipients of that favor are the penitent Israelites who were forgiven through Moses’ intercession. The two words are at the heart of God’s dealings with people. The first is חָנַן (khanan, “to be gracious, show favor”). It means to grant favor or grace to someone, grace meaning unmerited favor. All of God’s dealings are gracious, but especially in forgiving sins and granting salvation it is critical. Parallel to this is רָחַם (rakham), a word that means “show compassion, tender mercy.” It is a word that is related to the noun “womb,” the connection being in providing care and protection for that which is helpless and dependent – a motherly quality. In both of these constructions the verbs simply express what God will do, without explaining why. See further, J. R.
