Exodus 11:5 WBT

³  And the LORD gave the people favor in the sight of the Egyptians. Moreover, the man Moses [was] very great in the land of Egypt, in the sight of Pharaoh's servants, and in the sight of the people.

⁴  And Moses said, Thus saith the LORD, About midnight will I go out into the midst of Egypt:

⁵  And all the first-born in the land of Egypt shall die, from the first-born of Pharaoh that sitteth upon his throne, even to the first-born of the maid-servant that [is] behind the mill; and all the first-born of beasts.

⁶  And there shall be a great cry throughout all the land of Egypt, such as there hath been none like it, nor shall be like it any more.

⁷  But against any of the children of Israel shall not a dog move his tongue, against man or beast: that ye may know how the LORD doth put a difference between the Egyptians and Israel.
