English Standard Version
Chapter 8 27
We must go three days’ journey into the wilderness and sacrifice to the LORD our God as he tells us.” 28
So Pharaoh said, “I will let you go to sacrifice to the LORD your God in the wilderness; only you must not go very far away. Plead for me.” 29
Then Moses said, “Behold, I am going out from you and I will plead with the LORD that the swarms of flies may depart from Pharaoh, from his servants, and from his people, tomorrow. Only let not Pharaoh cheat again by not letting the people go to sacrifice to the LORD.” 30
So Moses went out from Pharaoh and prayed to the LORD. 31
And the LORD did as Moses asked, and removed the swarms of flies from Pharaoh, from his servants, and from his people; not one remained. 32
But Pharaoh hardened his heart this time also, and did not let the people go.
