O Lord God, to whom vengeance belongeth (comp. Deuteronomy 32:35, "To me belongeth vengeance and recompence;" and Jeremiah 51:56, where God is called "the Lord God of reeompences," as he is here—literally—"the Lord God of vengeances").
O God, to whom vengeance belongeth, show thyself; or, "shine forth"—make thy justice to appear; show thyself in thy character of a God who will by no means clear the guilty (Exodus 34:7).
