Exodus 8:29 BBE

²⁷  But we will go three days' journey into the waste land and make an offering to the Lord our God as he may give us orders.

²⁸  Then Pharaoh said, I will let you go to make an offering to the Lord your God in the waste land; but do not go very far away, and make prayer for me.

²⁹  And Moses said, When I go out from you I will make prayer to the Lord that the cloud of flies may go away from Pharaoh and from his people and from his servants tomorrow: only let Pharaoh no longer by deceit keep back the people from making their offering to the Lord.

³⁰  Then Moses went out from Pharaoh and made prayer to the Lord.

³¹  And the Lord did as Moses said, and took away the cloud of flies from Pharaoh and from his servants and from his people; not one was to be seen.
