15 But when Pharaoh saw that there was respite, he hardened his heart, and hearkened not unto them; as the LORD had spoken.
16 And the LORD said unto Moses, Say unto Aaron, Stretch out thy rod, and smite the dust of the earth, that it may become lice throughout all the land of Egypt.
17 And they did so; and Aaron stretched out his hand with his rod, and smote the dust of the earth, and there were lice upon man, and upon beast; all the dust of the earth became lice throughout all the land of Egypt.
18 And the magicians did so with their enchantments to bring forth lice, but they could not: and there were lice upon man, and upon beast.
19 Then the magicians said unto Pharaoh, This is the finger of God: and Pharaoh's heart was hardened, and he hearkened not unto them; as the LORD had spoken.
20 And the LORD said unto Moses, Rise up early in the morning, and stand before Pharaoh; lo, he cometh forth to the water; and say unto him, Thus saith the LORD, Let my people go, that they may serve me.
21 Else, if thou wilt not let my people go, behold, I will send swarms of flies upon thee, and upon thy servants, and upon thy people, and into thy houses: and the houses of the Egyptians shall be full of swarms of flies, and also the ground whereon they are.
