Some of the geographic details in Targum Pseudo-Jonathan are staggering. On Exodus 12:31, the Targum pauses to describe the map. The border of Mizraim extended four hundred pharsas — a rabbinic unit of distance equivalent to roughly four Roman miles each, making Egypt in this reading about sixteen hundred miles across. Goshen, where Moses and the sons of Israel dwelt, sat in the middle. Pharaoh's royal palace stood at the far entrance of the land.
And yet, when Pharaoh cried out to Moses and Aaron in the night of the Pascha, his voice was heard across the whole land, all the way to Goshen. The Targum is explicit about the miracle. No messenger rode through the night. No scroll was sent. Pharaoh's voice itself carried across hundreds of miles in a single wailing cry.
The content of the cry is a total reversal of every word Pharaoh had ever spoken to Moses. "Arise, go forth from among my people, both you and the sons of Israel; and go, worship before the Lord, as you have said." The king who had refused to release a single Hebrew for a three-day festival now begs the entire nation to leave, permanently, in the middle of the night.
The rabbis treated the miraculous acoustic as another of the night's signs. Pharaoh had silenced Israel for four hundred years. Now his own voice betrayed him across his entire kingdom, in one long scream of surrender.
Takeaway: Pharaoh wanted the world not to hear Israel's pain. The night of the Exodus made the whole kingdom hear his.
