Genesis 39:5
And it came to pass from the time that he had made him overseer in his house, and over all that he had, that the LORD blessed the Egyptian's house for Joseph's sake; and the blessing of the LORD was upon all that he had in the house, and in the field.
And it came to pass from the time that he had made him overseer in his house, and over all that he had,.... How long he was in this office is not certain; there must be some time for the following observation; and during all the time he was in it, it was easily discerned,
that the LORD blessed the Egyptian's house for Joseph's sake; that is, much more than before; everything under his hands succeeded before, but now much more abundantly; Potiphar's family was blessed with health, his substance increased, he grew rich and wealthy, and abounded with all good things:
and the blessing of the LORD was upon all that he had in the house,
and in the field; his domestic affairs prospered, his fields brought forth plentifully, his cattle were fruitful and stood well; every thing belonging to him within doors and without happily succeeded, through the blessing of God upon it, and all for Joseph's sake.
