22. So Moses stretched out his hand toward the sky, and for three days a thick darkness was all over the land of Egypt.
23. The Egyptians could not see one another, nor did anyone rise from his place for three days; but all the Israelites had natural light in their dwellings.
24. And Pharaoh called to Moses, and said, Go, serve the Lord; let your little ones also go with you; it is only your flocks and your herds that must not go.
25. But Moses said, You must give into our hand also sacrifices and burnt offerings, that we may sacrifice to the Lord our God.
26. Our livestock also shall go with us; there shall not a hoof be left behind; for of them must we take to serve the Lord our God, and we know not with what we must serve the Lord until we arrive there.
27. But the Lord made Pharaoh's heart stronger and more stubborn, and he would not let them go.
