Genesis 39:3. His master saw that the Lord was with him — Many of the heathen acknowledged a supreme God, and his overruling providence in the affairs of men, although they did not glorify him as God, but worshipped the creature with, and more than, the Creator: Potiphar, however, would doubtless learn from Joseph many things concerning the one living and true God; and proving by experience that his affairs prospered, and that Joseph ascribed this prosperity to the especial blessing of Jehovah, he might be inclined to believe that Jehovah blessed him for Joseph’s sake.

39:1-6 Our enemies may strip us of outward distinctions and ornaments; but wisdom and grace cannot be taken from us. They may separate us from friends, relatives, and country; but they cannot take from us the presence of the Lord. They may shut us from outward blessings, rob us of liberty, and confine us in dungeons; but they cannot shut us out from communion with God, from the throne of grace, or take from us the blessings of salvation. Joseph was blessed, wonderfully blessed, even in the house where he was a slave. God's presence with us, makes all we do prosperous. Good men are the blessings of the place where they live; good servants may be so, though mean and lightly esteemed. The prosperity of the wicked is, one way or other, for the sake of the godly. Here was a wicked family blessed for the sake of one good servant in it.Joseph fares well with his first master. "Potiphar." This is a racapitulation of the narrative in Genesis 37:"The Lord;" the God of covenant is with Joseph. "In the house." Joseph was a domestic servant. "And his master saw." The prosperity that attended all Joseph's doings was so striking as to show that the Lord was with him. "Set him over" - made him overseer of all that was in his house. "The Lord blessed the Mizrite's house." He blesses those who bless his own Genesis 12:3. "Beautiful in form and look" Genesis 29:17. This prepares the way for the following occurrence.3. his master saw that the Lord was with him—Though changed in condition, Joseph was not changed in spirit; though stripped of the gaudy coat that had adorned his person, he had not lost the moral graces that distinguished his character; though separated from his father on earth, he still lived in communion with his Father in heaven; though in the house of an idolater, he continued a worshipper of the true God. The heathens owned a supreme God, and his overruling providence in affairs, though they did not glorify him as God, but worshipped the creature with and more than the Creator, Romans 1:25.

In his hand, i.e. under his ministry, as this phrase is used, Exodus 4:13 Leviticus 8:36 Proverbs 26:6, and oft elsewhere.

And his master saw that the Lord was with him,.... He knew nothing of the spiritual and gracious presence of God that was with him, he was no judge of that; but he perceived by the ingenuity of his mind, by his ready and speedy learning the Egyptian language, by his dexterity in business, and by the prudence and faithfulness with which he did everything, that he was highly favoured by the divine Being, and had great endowments bestowed upon him, and was an extraordinary person for his age:

and that the Lord made all that he did to prosper in his hand; and though Potiphar might have no knowledge of the true Jehovah, whose name he uses, yet he might have a notion of a supreme Being, and that all outward prosperity was owing to him; and knowing Joseph to be an Hebrew, as it is plain his wife did, Genesis 39:14; and Jehovah to be the God of the Hebrews, he imputes all the prosperity that attended Joseph and his services unto his God.

And his master saw that the LORD was with him, and that the LORD made all that he did to prosper in his hand.
