Exodus 8:26 DBY

²⁴  And Jehovah did so; and there came dog-flies in a multitude into the house of Pharaoh, and [into] the houses of his bondmen; and throughout the land of Egypt, the land was corrupted by the dog-flies.

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

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

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!
