Exodus 11:6-8

Young's Literal Translation

⁶ and there hath been a great cry in all the land of Egypt, such as there hath not been, and such as there is not again.

⁷ `And against all the sons of Israel a dog sharpeneth not its tongue, from man even unto beast, so that ye know that Jehovah doth make a separation between the Egyptians and Israel;

⁸ and all these thy servants have come down unto me, and bowed themselves to me, saying, Go out, thou and all the people who [are] at thy feet; and afterwards I do go out;' -- and he goeth out from Pharaoh in the heat of anger.
