Counter-Arguments

The strongest case that this verse does not belong in this theme.

Israel-Specific Promises

The verse describes Pharaoh's hardened heart and God's foreknowledge of it, which is a narrative detail about the unfolding of events leading to Israel's exodus, not a promise, prophecy, or covenant specifically directed at ethnic Israel.
