And Joseph was {n} thirty years old when he stood before Pharaoh king of Egypt. And Joseph went out from the presence of Pharaoh, and went throughout all the land of Egypt.

(n) His age is mentioned both to show that his authority came from God, and also that he endured imprisonment and exile for twelve years or more.

Jamieson-Fausset-Brown Bible Commentary

went out . all the land-made an immediate survey to determine the site and size of the storehouses required for the different quarters of the country.

Matthew Henry's Concise Commentary

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.
