Exodus 8:25 ASV

²³  And I will put a division between my people and thy people: by to-morrow shall this sign be.

²⁴  And Jehovah did so; and there came grievous swarms of flies into the house of Pharaoh, and into his servants' houses: and in all the land of Egypt the land was corrupted by reason of the swarms of flies.

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

²⁶  And Moses said, It is not meet so to do; for we shall sacrifice the abomination of the Egyptians to Jehovah our God: lo, shall we sacrifice the abomination of the Egyptians before their eyes, and will 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.
