John Calvin Commentary Genesis 45:16

"And the report thereof was heard in Pharaoh`s house, saying, Joseph`s brethren are come: and it pleased Pharaoh well, and his servants." — Genesis 45:16 (ASV)

And the fame thereof was heard in Pharaoh’s house. What Moses now relates was earlier in the order of events. For before Joseph sent for his father, the report of the coming of his brethren had reached the palace. And Joseph would not have promised so confidently a home to his brethren in Egypt without the king’s permission.

Therefore, what Moses had previously alluded to, he now explains more fully; namely, that the king, with a ready and cheerful mind, declared his high esteem for Joseph by freely offering his father and brethren the most fertile part of Egypt for their dwelling. And from another statement of Moses, it appears that as long as Joseph lived, the Israelites were treated with clemency and kindness. For, in Exodus 1:8, the beginning of the tyranny and cruelty is said to have been made by his successor, to whom Joseph was unknown.
