Exodus 10:22-24

Darby Translation

²² And Moses stretched out his hand toward the heavens; and there was a thick darkness throughout the land of Egypt three days:

²³ they saw not one another, neither rose any from his place, for three days. But all the children of Israel had light in their dwellings.

²⁴ And Pharaoh called Moses and said, Go, serve Jehovah; only, let your flocks and your herds remain; let your little ones also go with you.
