Therefore they did set over them taskmasters to afflict them with their burdens. And they built for Pharaoh treasure cities, Pithom and Raamses.

Wesley's Notes

1:11 They set over them task - masters, to afflict them - With this very design. They not only made them serve, which was sufficient for Pharaoh's profit, but they made them serve with rigour, so that their lives became bitter to them; intending hereby to break their spirits, and to rob them of every thing in them that was generous: to ruin their health, and shorten their days, and so diminish their numbers: to discourage them from marrying, since their children would be born to slavery; and to oblige them to desert the Hebrews, and incorporate with the Egyptians. And 'tis to be feared the oppression they were under did bring over many of them to join with the Egyptians in their idolatrous worship; for we read, Jos 24:14, that they served other gods in Egypt; and we find, Eze 20:8, that God had threatned to destroy them for it, even while they were in the land of Egypt. Treasure - cities - To keep the king's money or corn, wherein a great part of the riches of Egypt consisted.

Jamieson-Fausset-Brown Bible Commentary

11. Therefore they did set over them taskmasters-Having first obliged them, it is thought, to pay a ruinous rent and involved them in difficulties, that new government, in pursuance of its oppressive policy, degraded them to the condition of serfs-employing them exactly as the laboring people are in the present day (driven in companies or bands), in rearing the public works, with taskmasters, who anciently had sticks-now whips-to punish the indolent, or spur on the too languid. All public or royal buildings, in ancient Egypt, were built by captives; and on some of them was placed an inscription that no free citizen had been engaged in this servile employment.

they built for Pharaoh treasure cities-These two store-places were in the land of Goshen; and being situated near a border liable to invasion, they were fortified cities (compare 2Ch 11:1-12:16). Pithom (Greek, Patumos), lay on the eastern Pelusiac branch of the Nile, about twelve Roman miles from Heliopolis; and Raamses, called by the Septuagint Heroopolis, lay between the same branch of the Nile and the Bitter Lakes. These two fortified cities were situated, therefore, in the same valley; and the fortifications, which Pharaoh commanded to be built around both, had probably the same common object, of obstructing the entrance into Egypt, which this valley furnished the enemy from Asia [Hengstenberg].

Matthew Henry's Concise Commentary

1:8-14 The land of Egypt became to Israel a house of bondage. The place where we have been happy, may soon become the place of our affliction; and that may prove the greatest cross to us, of which we said, This same shall comfort us. Cease from man, and say not of any place on this side heaven, This is my rest. All that knew Joseph, loved him, and were kind to his brethren for his sake; but the best and most useful services a man does to others, are soon forgotten after his death. Our great care should be, to serve God, and to please him who is not unrighteous, whatever men are, to forget our work and labour of love. The offence of Israel is, that he prospers. There is no sight more hateful to a wicked man than the prosperity of the righteous. The Egyptians feared lest the children of Israel should join their enemies, and get them up out of the land. Wickedness is ever cowardly and unjust; it makes a man fear, where no fear is, and flee, when no one pursues him. And human wisdom often is foolishness, and very sinful. God's people had task-masters set over them, not only to burden them, but to afflict them with their burdens. They not only made them serve for Pharaoh's profit, but so that their lives became bitter. The Israelites wonderfully increased. Christianity spread most when it was persecuted: the blood of the martyrs was the seed of the church. They that take counsel against the Lord and his Israel, do but imagine a vain thing, and create greater vexation to themselves.
