45 Pharaoh gave Joseph the name Zaphenath-Paneah and gave him Asenath daughter of Potiphera, priest of On,[1] to be his wife. And Joseph went throughout the land of Egypt.

46 Joseph was thirty years old when he entered the service of Pharaoh king of Egypt. And Joseph went out from Pharaoh's presence and traveled throughout Egypt. 47 During the seven years of abundance the land produced plentifully. 48 Joseph collected all the food produced in those seven years of abundance in Egypt and stored it in the cities. In each city he put the food grown in the fields surrounding it. 49 Joseph stored up huge quantities of grain, like the sand of the sea; it was so much that he stopped keeping records because it was beyond measure. 50 Before the years of famine came, two sons were born to Joseph by Asenath daughter of Potiphera, priest of On.

Commentary on Genesis 41:33-45

(Read Genesis 41:33-45)

Joseph gave good advice to Pharaoh. Fair warning should always be followed by good counsel. God has in his word told us of a day of trial before us, when we shall need all the grace we can have. Now, therefore, provide accordingly. Pharaoh gave Joseph an honourable testimony. He is a man in whom the spirit of God is; and such men ought to be valued. Pharaoh puts upon Joseph marks of honour. He gave him such a name as spoke the value he had for him, Zaphnath-paaneah, "a revealer of secrets." This preferment of Joseph encourages all to trust in God. Some translate Joseph's new name, "the saviour of the world." The brightest glories, even of the upper world, are put upon Christ, the highest trust lodged in his hand, and all power given him, both in heaven and earth.

Commentary on Genesis 41:46-57

(Read Genesis 41:46-57)

In the names of his two sons, Manasseh and Ephraim, Joseph owned the Divine providence. 1. He was made to forget his misery. 2. He was made fruitful in the land of his affliction. The seven plenteous years came, and were ended. We ought to look forward to the end of the days, both of our prosperity and of our opportunity. We must not be secure in prosperity, nor slothful in making good use of opportunity. Years of plenty will end; what thy hand finds to do, do it; and gather in gathering time. The dearth came, and the famine was not only in Egypt, but in other lands. Joseph was diligent in laying up, while the plenty lasted. He was prudent and careful in giving out, when the famine came. Joseph was engaged in useful and important labours. Yet it was in the midst of this his activity that his father Jacob said, Joseph is not! What a large portion of our troubles would be done away if we knew the whole truth! Let these events lead us to Jesus. There is a famine of the bread of life throughout the whole earth. Go to Jesus, and what he bids you, do. Attend to His voice, apply to him; he will open his treasures, and satisfy with goodness the hungry soul of every age and nation, without money and without price. But those who slight this provision must starve, and his enemies will be destroyed.
