Exodus 8:25-28
25
Pharaoh called for Moses and for Aaron, and said, "Go, sacrifice to your God in the land!"
26
Moses said, "It isn't appropriate to do so; for we shall sacrifice the abomination of the Egyptians to Yahweh our God. Behold, shall we sacrifice the abomination of the Egyptians before their eyes, and won't they stone us?
27
We will go three days' journey into the wilderness, and sacrifice to Yahweh our God, as he shall command us."
28
Pharaoh said, "I will let you go, that you may sacrifice to Yahweh your God in the wilderness, only you shall not go very far away. Pray for me."
