25 Then Pharaoh called for Moses and for Aaron and said, Go ye, sacrifice to your God in the land of Egypt.
26 And Moses replied, It is not convenient to do so; for we shall sacrifice the abomination of the Egyptians to the Lord our God. Behold, if we sacrifice the abomination of the Egyptians before their eyes, will they not stone us?
27 We will go three days’ journey into the wilderness and sacrifice to the Lord our God as he has said unto us.
28 And Pharaoh said, I will let you go that ye may sacrifice to the Lord your God in the wilderness; only ye shall not go very far away; pray for me.
29 And Moses answered, Behold, as I go out from thy presence, I will intreat the Lord that the swarms of flies may depart from Pharaoh, from his slaves, and from his people tomorrow; if Pharaoh will not deal deceitfully any more in not letting the people go to sacrifice to the Lord.
30 Then Moses went out from Pharaoh, and prayed unto the Lord.
31 And the Lord did according to the word of Moses, and he removed the swarms of flies from Pharaoh, from his slaves, and from his people; there remained not one.
