Exodus 8:25-29

25And Pharaoh called Moses and Aaron, and said, Go, sacrifice to your 1God in the land.

26And Moses said, It is not proper to do so; for we should sacrifice the abomination of the Egyptians to Jehovah our 2God: lo, if we sacrificed the abomination of the Egyptians before their eyes, would they not stone us?

27We will go three days' journey into the wilderness, and sacrifice to Jehovah our 3God, as he shall command us.

28And Pharaoh said, I will let you go, that you may sacrifice to Jehovah your 4God in the wilderness; only, go not very far away: intreat for me!

29And 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.
