Targum zu Schemot 12:33

When Mosheh and Aharon, and the sons of Israel, heard the voice of Pharoh's weeping, they were not mindful, until he came himself, and all his servants, and all the Mizraee, and urged all the people of the house of Israel, that they might hasten to send them forth from the land; For, said they, if they prolong here one hour more, behold, we are all dead.

For, said the Mizraee, if Israel delay one hour (longer), behold, all Mizraim dies.
