Exodus 10:21-29

21And Yhwh said unto Moses, Stretch out thine hand toward heaven, that there may be darkness over the land of Egypt, even darkness which may be felt.1 22And Moses stretched forth his hand toward heaven; and there was a thick darkness in all the land of Egypt three days: 23They saw not one another, neither rose any from his place for three days: but all the children of Israel had light in their dwellings.

24And Pharaoh called unto Moses, and said, Go ye, serve Yhwh; only let your flocks and your herds be stayed: let your little ones also go with you. 25And Moses said, Thou must give us also sacrifices and burnt offerings, that we may sacrifice unto Yhwh our God.2 26Our cattle also shall go with us; there shall not an hoof be left behind; for thereof must we take to serve Yhwh our God; and we know not with what we must serve Yhwh, until we come thither.

27But Yhwh hardened Pharaoh’s heart, and he would not let them go. 28And Pharaoh said unto him, Get thee from me, take heed to thyself, see my face no more; for in that day thou seest my face thou shalt die. 29And Moses said, Thou hast spoken well, I will see thy face again no more.
