Abominable Sacrifices
Then Pharaoh summoned Moses and Aaron and said, “Go sacrifice to your God within the land.” But Moses replied, “It is not right to do so, for what we sacrifice to the LORD, our God, is abhorrent to the Egyptians. If we sacrifice what is abhorrent to the Egyptians before their very eyes, will they not stone us?
Exodus 8:21-22
Lambs and sheep were sacred to their gods Amum and Khnum. Amum was the king of gods, and later joined with the sun god as Amun-Ra. Khnum was the god who created each individual human, controlled the water level of the Nile, and was one of the oldest gods of Egypt. The idea of sacrificing a lamb or sheep was probably highly offensive to the Egyptians.
