Exodus 8:26-27

26But Moses said, “It is not permissible for us to do so, because we will sacrifice to the Lord our God 1that which is 2an abomination to the Egyptians. If we sacrifice 3that which is an abomination to the Egyptians before their eyes, will they not stone us?

27We must go a 4three days’ journey into the wilderness and sacrifice to the Lord our God, just as He 5commands us.”
