Two grinding in the mill; one shall be taken, and one let go.
And every first-born in the land of Egypt shall die, from the first-born of Pharaoh sitting upon his throne, even to the first-born of the maid which is behind the two mill-stones; and every first-born of quadruped.
Take the two mill-stones and grind flour, and uncover thy veil; strip off the train, uncover the leg, pass through the rivers.
Then shall be two in the field; one shall be taken, and one is let go;
Two females shall be grinding together; one shall be taken, and the other let go.
He shall not take the two mill-stones as a pledge, and the rider, for it is taking the soul as a pledge.
