Shemot - Exodus
5 And Moses said unto Pharaoh: 'Have thou this glory over me; against what time shall I entreat for thee, and for thy servants, and for thy people, that the frogs be destroyed from thee and thy houses, and remain in the river only?'
11 But when Pharaoh saw that there was respite, he hardened his heart, and hearkened not unto them; as HaShem had spoken.
13 And they did so; and Aaron stretched out his hand with his rod, and smote the dust of the earth, and there were gnats upon man, and upon beast; all the dust of the earth became gnats throughout all the land of Egypt.
15 Then the magicians said unto Pharaoh: 'This is the finger of G-d'; and Pharaoh's heart was hardened, and he hearkened not unto them; as HaShem had spoken.
16 And HaShem 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 HaShem: Let My people go, that they may serve Me.
17 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.
20 And HaShem did so; and there came grievous swarms of flies into the house of Pharaoh, and into his servants' houses; and in all the land of Egypt the land was ruined by reason of the swarms of flies.
22 And Moses said: 'It is not meet so to do; for we shall sacrifice the abomination of the Egyptians to HaShem our G-d; lo, if we sacrifice the abomination of the Egyptians before their eyes, will they not stone us?
25 And Moses said: 'Behold, I go out from thee, and I will entreat HaShem that the swarms of flies may depart from Pharaoh, from his servants, and from his people, tomorrow; only let not Pharaoh deal deceitfully any more in not letting the people go to sacrifice to HaShem.'
26 And Moses went out from Pharaoh, and entreated HaShem.
27 And HaShem did according to the word of Moses; and He removed the swarms of flies from Pharaoh, from his servants, and from his people; there remained not one.
28 And Pharaoh hardened his heart this time also, and he did not let the people go.
