And I will distinguish in that day the land of Goshen, in which my people dwell, that no dog-flies shall be there; that thou mayest know that I Jehovah am in the midst of the land.
And Jehovah will distinguish between the cattle of Israel and the cattle of Egypt; and there shall nothing die of all that the children of Israel have.
But against any of the children of Israel shall not a dog move his tongue, against man or beast; that ye may know that Jehovah distinguisheth between the Egyptians and Israel.
And how shall it be known then that I have found grace in thine eyes I and thy people? Is it not by thy going with us? so shall we be distinguished, I and thy people, from every people that is on the face of the earth.
