Таргум к Шмот 16:21

And they gathered from the time of the dawn until the fourth hour of the day, every man according to his eating; but at the fourth hour, when the sun had waxed hot upon it, it liquefied, and made streams of water, which flowed away into the Great Sea; and wild animals that were clean, and cattle, came to drink of it, and the sons of Israel hunted, and ate them.

Became as streams.
