Exodus 11:5

And smote all the firstborn in Egypt; the chief of their strength in the tabernacles of Ham:

For I will pass through the land of Egypt this night, and will smite all the firstborn in the land of Egypt, both man and beast; and against all the gods of Egypt I will execute judgment: I am the Lord.

And it came to pass, that at midnight the Lord smote all the firstborn in the land of Egypt, from the firstborn of Pharaoh that sat on his throne unto the firstborn of the captive that was in the dungeon; and all the firstborn of cattle.

And it came to pass, when Pharaoh would hardly let us go, that the Lord slew all the firstborn in the land of Egypt, both the firstborn of man, and the firstborn of beast: therefore I sacrifice to the Lord all that openeth the matrix, being males; but all the firstborn of my children I redeem.

And I say unto thee, Let my son go, that he may serve me: and if thou refuse to let him go, behold, I will slay thy son, even thy firstborn.

Two women shall be grinding at the mill; the one shall be taken, and the other left.

He smote also all the firstborn in their land, the chief of all their strength.

Who smote the firstborn of Egypt, both of man and beast.

To him that smote Egypt in their firstborn: for his mercy endureth for ever:

Through faith he kept the passover, and the sprinkling of blood, lest he that destroyed the firstborn should touch them.

Take the millstones, and grind meal: uncover thy locks, make bare the leg, uncover the thigh, pass over the rivers.

But the Philistines took him, and put out his eyes, and brought him down to Gaza, and bound him with fetters of brass; and he did grind in the prison house.

They took the young men to grind, and the children fell under the wood.
