Exodus 10:21–29

²¹And the Lord said to Moses: Stretch out thy hand towards heaven: and may there be darkness upon the land of Egypt so thick that it may be felt.

²²And Moses stretched forth his hand towards heaven: and there came horrible darkness in all the land of Egypt for three days.

²³No man saw his brother, nor moved himself out of the place where he was: but wheresoever the children of Israel dwelt, there was light.

²⁴And Pharao called Moses and Aaron, and said to them: Go, sacrifice to the Lord: let your sheep only, and herds remain, let your children go with you.

²⁵Moses said: Thou shalt give us also sacrifices and burnt-offerings, to the Lord our God.

²⁶All the flocks shall go with us; there shall not a hoof remain of them: for they are necessary for the service of the Lord our God: especially as we know not what must be offered, till we come to the very place.

²⁷And the Lord hardened Pharao’s heart, and he would not let them go.

²⁸And Pharao said to Moses: Get thee from me, and beware thou see not my face any more: in what day soever thou shalt come in my sight, thou shalt die.

²⁹Moses answered: So shall it be as thou hast spoken, I will not see thy face any more.
