Exodus 8:25 DBY

²³  And I will put a separation between my people and thy people; to-morrow shall this sign be.

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.
