Rabbi Simon said: On the fourth day the Israelites encamped by the edge of the sea, and to the south of the sea. The Egyptians were floating like skin-bottles upon the surface of the waters, and a north wind went forth and cast them opposite the camp of Israel, and the Israelites went and saw them, and they recognized them, and they said: These (here) were the officials of the palace of Pharaoh, and those (there) were the taskmasters, and they recognized every one, as it is said, "And Israel saw the Egyptians || dead upon the sea shore" (Ex. 14:30).
