15But when Pharaoh saw that there was peace for a time, he made his heart hard and did not give ear to them, as the Lord had said.
16And the Lord said to Moses, Say to Aaron, Let your rod be stretched out over the dust of the earth so that it may become insects through all the land of Egypt.
17And they did so; and Aaron, stretching out the rod in his hand, gave a touch to the dust of the earth, and insects came on man and on beast; all the dust of the earth was changed into insects through all the land of Egypt.
18And the wonder-workers with their secret arts, attempting to make insects, were unable to do so: and there were insects on man and on beast.
19Then the wonder-workers said to Pharaoh, This is the finger of God: but Pharaoh's heart was hard, and he did not give ear to them, as the Lord had said.
20And the Lord said to Moses, Get up early in the morning and take your place before Pharaoh when he comes out to the water; and say to him, This is what the Lord says: Let my people go to give me worship.
21For if you do not let my people go, see, I will send clouds of flies on you and on your servants and on your people and into their houses; and the houses of the Egyptians and the land where they are will be full of flies.
