Complete Commentary on the Whole Bible, by Matthew Henry, at sacred-texts.com
(Exo 1:1-7) The children of Israel increase in Egypt after the death of Joseph.
(Exo 1:8-14) They are oppressed, but multiply exceedingly.
(Exo 1:15-22) The men-children destroyed.
During more than 200 years, while Abraham, Isaac, and Jacob lived at liberty, the Hebrews increased slowly; only about seventy persons went down into Egypt. There, in about the same number of years, though under cruel bondage, they became a large nation. This wonderful increase was according to the promise long before made unto the fathers. Though the performance of God's promises is sometimes slow, it is always sure.
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.
The Egyptians tried to destroy Israel by the murder of their children. The enmity that is in the seed of the serpent, against the Seed of the woman, makes men forget all pity. It is plain that the Hebrews were now under an uncommon blessing. And we see that the services done for God's Israel are often repaid in kind. Pharaoh gave orders to drown all the male children of the Hebrews. The enemy who, by Pharaoh, attempted to destroy the church in this its infant state, is busy to stifle the rise of serious reflections in the heart of man. Let those who would escape, be afraid of sinning, and cry directly and fervently to the Lord for assistance.
