18. And he went out from Pharaoh, and entreated the LORD.
19. And the LORD turned a mighty strong west wind, which took away the locusts, and cast them into the Red sea; there remained not one locust in all the land of Egypt.
20. But the LORD hardened Pharaoh's heart, so that he would not let the children of Israel go.
21. And the LORD said unto Moses,
22. And Moses stretched forth his hand toward heaven; and there was a thick darkness in all 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 unto Moses, and said, Go, serve the LORD; only let your flocks and your herds be left behind: let your little ones also go with you.
25. And Moses said, you must give us also sacrifices and burnt offerings, that we may sacrifice unto the LORD our God.
26. Our cattle 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 come there.
27. But the LORD hardened Pharaoh's heart, and he would not let them go.
