Now there arose up a new king over Egypt, which {c} knew not Joseph.

(c) He did not consider how God had preserved Egypt for the sake of Joseph.

Wesley's Notes

1:8 There arose a new king (after several successions in Joseph's time) which knew not Joseph - All that knew him loved him, and were kind to his relations for his sake; but when he was dead he was soon forgotten, and the remembrance of the good offices he had done was either not retained or not regarded. If we work for men only, our works at farthest will die with us; if for God, they will follow us, Rev 14:13.

Jamieson-Fausset-Brown Bible Commentary

8. Now there arose up a new king-About sixty years after the death of Joseph a revolution took place-by which the old dynasty was overthrown, and upper and lower Egypt were united into one kingdom. Assuming that the king formerly reigned in Thebes, it is probable that he would know nothing about the Hebrews; and that, as foreigners and shepherds, the new government would, from the first, regard them with dislike and scorn.

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.
