All countries came into Egypt - to buy - As there had not been a sufficiency of rains, vapours, etc., to swell the Nile, to effect a proper inundation in Egypt, the same cause would produce drought, and consequently scarcity, in all the neighboring countries; and this may be all that is intended in the text.
1. As the providence of God evidently led the butler and baker of Pharaoh, as well as the king himself, to dream the prophetic dreams mentioned in this and the preceding chapter, so his Spirit in Joseph led to the true interpretation of them. What a proof do all these things give us of a providence that is so general as to extend its influence to every part, and so particular as to notice, influence, and direct the most minute circumstances! Surely God "has way every where, and all things serve his will."
2. Dreams have been on one hand superstitiously regarded, and on the other skeptically disregarded. That some are prophetic there can be no doubt; that others are idle none can hesitate to believe. Dreams may be divided into the six following kinds:
1. Those which are the mere nightly result of the mind's reflections and perplexities during the business of the day.
2. Those which spring from a diseased state of the body, occasioning startings, terrors, etc.
3. Those which spring from an impure state of the heart, mental repetitions of those acts or images of illicit pleasure, riot, and excess, which form the business of a profligate life.
4. Those which proceed from a diseased mind, occupied with schemes of pride, ambition, grandeur, etc. These, as forming the characteristic conduct of the life, are repeatedly reacted in the deep watches of the night, and strongly agitate the soul with illusive enjoyments and disappointments.
5. Those which come immediately from Satan, which instill thoughts and principles opposed to truth and righteousness, leaving strong impressions on the mind suited to its natural bent and turn, which, in the course of the day, by favoring circumstances, may be called into action.
6. Those which come from God, and which necessarily lead to him, whether prophetic of future good or evil, or impressing holy purposes and heavenly resolutions. Whatever leads away from God, truth, and righteousness, must be from the source of evil; whatever leads to obedience to God, and to acts of benevolence to man, must be from the source of goodness and truth. Reader, there is often as much superstition in disregarding as in attending to dreams; and he who fears God will escape it in both.

And all countries came into Egypt to Joseph for to buy corn,.... All the neighbouring nations (Syria, Arabia, Palestine, Canaan, &c.), when they heard there was corn there for money, came from all parts for it, and were glad to get it at such expense and trouble:
because that the famine was so sore in all lands; that there was no bread to be got for money elsewhere. It is thought by many, that for this care of Joseph in laying up provision against this time of need, and which was the preservation of the Egyptians, he was worshipped by them under various names; as the Apis, which was an ox, a sign of fruitfulness; and Serapis, sometimes figured as a young man carrying a basket of bread on his head; and Osiris, who is sometimes represented with a bushel on his head. However, this is certain, that he was an eminent type of Christ in all this, both in his estate of humiliation and exaltation: as Joseph was wrongly charged by his mistress, so was Christ falsely accused by the Jews; as he was cast into prison and bound there, so Christ was taken and bound as a prisoner; as Joseph was raised to great honour and glory in Pharaoh's court, so Christ was exalted by his Father, and crowned with glory and honour; and if the new name given him, "Zaphnathpaaneah", signifies the Saviour of the world, as some interpret it, it agrees well with Christ, who was sent into the world for that purpose; and indeed, if it means a revealer of secrets, it suits with him, who hath declared his Father's mind and will, and revealed the mysteries of his grace to the sons of men: and as Joseph had all the stores of corn under his care, and the needy were bid to go to him for it, so Christ has all the treasures of grace in his hand, and all that are sensible of their need of it are directed to go to him for it; and it is from him that men of all nations and countries receive grace for grace, and have all their supplies, and spiritual sustenance and nourishment.

The famine was sore in all lands--that is, the lands contiguous to Egypt--Canaan, Syria, and Arabia.
