The final hour of the Egyptian captivity is captured in a sentence of panic. Targum Pseudo-Jonathan on Exodus 12:33 describes how Moses, Aaron, and the sons of Israel heard Pharaoh's weeping and did not rush. They were not going to be moved by the cry of a king who had refused nine previous warnings. They waited until Pharaoh himself, with his servants and every remaining Mizraee, came to urge them out.
The reason the Egyptians gave is electrifying: "if they prolong here one hour more, behold, we are all dead." The Targum turns the moment into a theological calculation by the Mizraee. They have just seen what one night of divine justice can do. Another hour, and the rest of them will not survive.
That is a striking inversion. For centuries, Pharaoh's Egypt had assumed it controlled the Hebrews' clock. Every sunrise the slaves rose when their masters rose. Every sundown the slaves stopped when permitted. Now the Egyptians are the ones counting minutes. An hour, they say. If they stay an hour more, we are finished.
The rabbis noted that Moses and the elders did not respond to Pharaoh's first screams. They waited until Egypt came to them. The Targum's portrait of that delay is deliberate. Israel had learned patience in four hundred years of slavery. On the night of liberation, they used it once more, on their own terms.
Takeaway: Israel did not leave when Pharaoh cried. Israel left when Egypt was begging at the door.
