1 And afterward Moses and Aaron went in, and told Pharaoh, Thus saith the LORD God of Israel, Let my people go, that they may hold a feast unto me in the wilderness. 2 And Pharaoh said, Who is the LORD, that I should obey his voice to let Israel go? I know not the LORD, neither will I let Israel go. 3 And they said, The God of the Hebrews hath met with us: let us go, we pray thee, three days' journey into the desert, and sacrifice unto the LORD our God; lest he fall upon us with pestilence, or with the sword. 4 And the king of Egypt said unto them, Wherefore do ye, Moses and Aaron, let the people from their works? get you unto your burdens. 5 And Pharaoh said, Behold, the people of the land now are many, and ye make them rest from their burdens. 6 And Pharaoh commanded the same day the taskmasters of the people, and their officers, saying, 7 Ye shall no more give the people straw to make brick, as heretofore: let them go and gather straw for themselves. 8 And the tale of the bricks, which they did make heretofore, ye shall lay upon them; ye shall not diminish ought thereof: for they be idle; therefore they cry, saying, Let us go and sacrifice to our God. 9 Let there more work be laid upon the men, that they may labour therein; and let them not regard vain words. 10 And the taskmasters of the people went out, and their officers, and they spake to the people, saying, Thus saith Pharaoh, I will not give you straw. 11 Go ye, get you straw where ye can find it: yet not ought of your work shall be diminished. 12 So the people were scattered abroad throughout all the land of Egypt to gather stubble instead of straw. 13 And the taskmasters hasted them, saying, Fulfil your works, your daily tasks, as when there was straw. 14 And the officers of the children of Israel, which Pharaoh's taskmasters had set over them, were beaten, and demanded, Wherefore have ye not fulfilled your task in making brick both yesterday and to day, as heretofore? 15 Then the officers of the children of Israel came and cried unto Pharaoh, saying, Wherefore dealest thou thus with thy servants? 16 There is no straw given unto thy servants, and they say to us, Make brick: and, behold, thy servants are beaten; but the fault is in thine own people. 17 But he said, Ye are idle, ye are idle: therefore ye say, Let us go and do sacrifice to the LORD. 18 Go therefore now, and work; for there shall no straw be given you, yet shall ye deliver the tale of bricks. 19 And the officers of the children of Israel did see that they were in evil case, after it was said, Ye shall not minish ought from your bricks of your daily task. 20 And they met Moses and Aaron, who stood in the way, as they came forth from Pharaoh: 21 And they said unto them, The LORD look upon you, and judge; because ye have made our savour to be abhorred in the eyes of Pharaoh, and in the eyes of his servants, to put a sword in their hand to slay us. 22 And Moses returned unto the LORD, and said, Lord, wherefore hast thou so evil entreated this people? why is it that thou hast sent me? 23 For since I came to Pharaoh to speak in thy name, he hath done evil to this people; neither hast thou delivered thy people at all.
[AD 430] Augustine of Hippo on Exodus 5:1
Some ask how the people can be told that God gave the order that he would lead them from Egypt into the land of Canaan, while Pharaoh was told that they wanted to make three days’ journey into the desert to offer sacrifice to their god by his command. But the passage should be understood thus: although God knew what he was going to do and knew that Pharaoh would not agree to dismiss the people, that fact was to be stated first that would also happen first, if Pharaoh let the people go. The contumacy of Pharaoh and his courtiers merited everything that happened, to which the Scripture afterward attests. God is not lying when he commands what he knows is not going to be done by the one he commands; his purpose is to obtain a just judgment.

[AD 407] John Chrysostom on Exodus 5:2
Let us then become lowly, that we may be high. For most utterly does arrogance abase. This abased Pharaoh. For, “I know not,” he says, “the Lord,” and he became inferior to flies and frogs and the locusts, and after that with his very arms and horses was he drowned in the sea. In direct opposition to him, Abraham says, “I am dust and ashes” and prevailed over countless barbarians, and having fallen into the midst of Egyptians, returned, bearing a trophy more glorious than the former, and, cleaving to this virtue, grew ever more high.

[AD 430] Augustine of Hippo on Exodus 5:9
When both the good and the bad do the same things and suffer the same things, they are to be distinguished by their intentions, not by their acts and penalties. Pharaoh oppressed the people of God with hard labors; Moses afflicted the same people, who had fallen into idolatry, with severe punishments. They did the same things, but they did not aim at the same result. The former was puffed up with pride of power, the latter was animated by love.

[AD 379] Basil of Caesarea on Exodus 5:17
Even Pharaoh knew that it was proper for one to seek God when he was unoccupied, and for this reason he reproached Israel: “You are unoccupied, you are idle, and you say, ‘We shall offer prayers to the Lord, our God.’ ” Now leisure itself is good and useful to him who is unoccupied, since it produces quiet for the acquisition of salutary doctrines. But the leisure of the Athenians was evil, “who used to spend all their leisure telling or listening to something new.” Even at the present time some imitate this, misusing the leisure of life for the discovery of some newer teaching.

[AD 391] Pacian of Barcelona on Exodus 5:20
In Moses and Aaron the law and the prophets are prefigured. A sick soul often murmurs to itself against the sacred words. After it has begun to hear and follow the heavenly words, the opposition of the Egyptian king—that is, the temptation of an evil spirit—rises up. So the physician should carefully make known to the soul that is making progress which temptations will attack it, so that it can carefully prepare itself for the snares of an evil spirit.

[AD 430] Augustine of Hippo on Exodus 5:22
The words that Moses speaks to the Lord are not words of contumacy or indignation but of inquiry and prayer. This fact is clear from the way the Lord answered him. For he did not accuse him of infidelity but revealed what he was about to do.
