Exodus 8:22

And the LORD shall sever between the cattle of Israel and the cattle of Egypt: and there shall nothing die of all that is the children’s of Israel.

Then shall ye return, and discern between the righteous and the wicked, between him that serveth God and him that serveth him not.

They saw not one another, neither rose any from his place for three days: but all the children of Israel had light in their dwellings.

Thus will I execute judgments in Egypt: and they shall know that I am the LORD.

And the LORD did that thing on the morrow, and all the cattle of Egypt died: but of the cattle of the children of Israel died not one.

The LORD shall send the rod of thy strength out of Zion: rule thou in the midst of thine enemies.

And the blood shall be to you for a token upon the houses where ye are: and when I see the blood, I will pass over you, and the plague shall not be upon you to destroy you, when I smite the land of Egypt.

Only in the land of Goshen, where the children of Israel were, was there no hail.

And Moses said unto him, As soon as I am gone out of the city, I will spread abroad my hands unto the LORD; and the thunder shall cease, neither shall there be any more hail; that thou mayest know how that the earth is the LORD’s.

Thus saith the LORD, In this thou shalt know that I am the LORD: behold, I will smite with the rod that is in mine hand upon the waters which are in the river, and they shall be turned to blood.

And he said, To morrow. And he said, Be it according to thy word: that thou mayest know that there is none like unto the LORD our God.

For God is my King of old, working salvation in the midst of the earth.
