Exodus 8:27-29

Darby Translation

²⁷ We will go three days' journey into the wilderness, and sacrifice to Jehovah our God, as he shall command us.

²⁸ And Pharaoh said, I will let you go, that you may sacrifice to Jehovah your God in the wilderness; only, go not very far away: intreat for me!

²⁹ And Moses said, Behold, I go out from thee, and will intreat Jehovah; and the dog-flies will depart from Pharaoh, from his bondmen, and from his people, to-morrow; only let not Pharaoh deal deceitfully any more in not letting the people go to sacrifice to Jehovah.
