What Does Exodus 8:12 Mean?

So Moses and Aaron went out from Pharaoh, and Moses cried to the LORD about the frogs, as he had agreed with Pharaoh.

The intercession of Moses for Pharaoh's relief is reported in verse 12: Moses and Aaron leave the royal presence, and Moses prays to YHWH about the frogs "as he had agreed with Pharaoh." The phrase "as he had agreed" (Hebrew: livdar phar'oh, literally "according to the word/thing to/about Pharaoh") ties the prayer to the Pharaoh-specified timing: Moses prays at the time and in the manner consistent with the agreement made in verses 9-11. The prayer is not spontaneous but covenantally structured: it happens according to the terms Moses and Pharaoh established.

The fact that Moses prays for Pharaoh at all is remarkable: Moses is praying for the relief of the king who has enslaved his people and who has refused every divine command. The intercession of Moses for Pharaoh's comfort is the model of prophetic intercession beyond the prophet's own community.

Abraham interceded for Sodom (Genesis 18); Moses will intercede for Israel repeatedly (Exodus 32-34); here Moses intercedes for Pharaoh. The willingness to pray for the adversary's relief, when YHWH has made it part of the sign-system, is not a concession to Pharaoh's authority but an extension of the sign's reach: the prayer is itself part of the demonstration.

The cry (Hebrew: vayitzak) of Moses to YHWH has an urgency implied by the verb: Moses did rather than request but cried out. Whether this urgency reflects distress at having to intercede for the oppressor or eagerness to demonstrate YHWH's responsiveness is not specified. What is clear is that Moses fulfilled his agreement: he prayed, and what followed (verse 13) was the answer YHWH gave. Moses' fidelity to his word to Pharaoh is part of the integrity of the demonstration: Moses does what he said he would do, and YHWH does what the prayer requests.
