Exodus 11:6 YLT

⁴  And Moses saith, 'Thus said Jehovah, About midnight I am going out into the midst of Egypt,

⁵  and every first-born in the land of Egypt hath died, from the first-born of Pharaoh who is sitting on his throne, unto the first-born of the maid-servant who 'is' behind the millstones, and all the first-born of beasts;

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.
