Exodus 8:27-29

Wycliffe Bible

²⁷ We shall go the way of three days into wilderness, and we shall make sacrifice to our Lord God, as he commanded us. (We shall make a journey for three days into the wilderness, and we shall offer sacrifices to the Lord our God, as he commanded us.)

²⁸ And Pharaoh said, I shall deliver you, that ye make sacrifice to the Lord your God in desert (I shall let you go, so that ye can offer sacrifices to the Lord your God in the wilderness); nevertheless go ye not (any) further; (and) pray ye for me.

²⁹ And Moses said, I shall go out from thee, and I shall pray (to) the Lord; and the fly, that is, the multitude of flies, shall go away from Pharaoh, and from his servants, and (from) his people, tomorrow; nevertheless do not thou more deceive me, that thou deliver not the people to make sacrifice to the Lord (but do not thou deceive me again, and not allow the people to go, and offer sacrifices to the Lord).
