“Notice that this child's name too is suggestive of gratitude. "Not only did he grant me forgetfulness of my distress," he is saying, "but he also made me prosper in the land where I suffered such awful humiliation as to be reduced to the limit and run a risk to life itself."”

“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. Next: Genesis Chapter 42”

“Ephraim. That is, fruitful, or growing. (Challoner) — Being in the plural number, it means “productions.” — Poverty; where I have been poor and afflicted, though now advanced in honour. (Haydock)”

“The second son he named Ephraim, i.e., double-fruitfulness; "for God hath made me fruitful in the land of my affliction." Even after his elevation Egypt still continued the land of affliction, so that in this word we may see one trace of a longing for the promised land.”
