But the Lord was with Joseph. It appears, from the testimony of the Psalmist just cited, that Joseph's extreme sufferings were not immediately alleviated. The Lord purposely suffered him to be reduced to extremity, that he might bring him back as from the grave. We know that as the light of the sun is most clearly seen when we are looking from a dark place; so, in the darkness of our miseries, the grace of God shines more brightly when, beyond expectation, he succors us. Moreover, Moses says, the Lord was with Joseph, because he extended this grace or mercy towards him; whence we may learn, that God, even when he delivers us from unjust violence, or when he assists us in a good cause, is yet induced to do so by his own goodness. For since we are unworthy that he should grant us his help, the cause of its communication must be in himself; seeing that he is merciful. Certainly if merits, which should lay God under obligation, are to be sought for in men, they would have been found in Joseph; yet Moses declares that he was assisted by the gratuitous favor of God. This, however, is no obstacle to his leaving received the reward of his piety, which is perfectly consistent with the gratuitous kindness of God. The manner of exercising this kindness is also added; namely, that the Lord gave him favor with the keeper of the prison. There is, indeed, no doubt that Joseph was acceptable to the keeper for many reasons: for even virtue conciliates favor to itself; and Moses has before shown that the holy man was amiable in many ways; but because it often happens that the children of God are treated with as great inhumanity as if they were the worst of all men, Moses expressly states that the keeper of the prison, at length, became humane; because his mind, which was not spontaneously disposed to equity, had been divinely inclined to it. Therefore, that the keeper of the prison, having laid aside his cruelty, acted with kindness and gentleness, was a change which proceeded from God, who governs the hearts of men according to his own will. But it is a wonder that the keeper of the prison did not fear lest he should incur the displeasure of Potiphar: and even that Potiphar himself, who without difficulty could have interfered, should yet have suffered a man whom he mortally hated to be thus kindly and liberally treated. It may be answered with truth, that his cruelty had been divinely restrained: but it is also probable that he had suspected, and at length, been made acquainted with the subtle scheme of his wife. Although, however, he might be appeased towards holy Joseph, he was unwilling to acquit him to his own dishonor. Meanwhile the remarkable integrity of Joseph manifests itself in this, that when he is made the guard of the prison, and has the free administration of it, he nevertheless does not attempt to escape, but waits for the proper season of his liberation.

The Lord was with Joseph - It is but of little consequence where the lot of a servant of God may be cast; like Joseph he is ever employed for his master, and God honors him and prospers his work.
1. He who acknowledges God in all his ways, has the promise that God shall direct all his steps. Joseph's captivity shall promote God's glory; and to this end God works in him, for him, by him. Even the irreligious can see when the Most High distinguishes his followers. Joseph's master saw that Jehovah was with him; and from this we may learn that the knowledge of the true God was in Egypt, even before the time of Joseph, though his worship was neither established nor even tolerated there. Both Abraham and Isaac had been in Egypt, and they had left a savor of true godliness behind them.
2. Joseph's virtue in resisting the solicitations of his mistress was truly exemplary. Had he reasoned after the manner of men, he might have soon found that the proposed intrigue might be carried on with the utmost secrecy and greatly to his secular advantage. But he chose to risk all rather than injure a kind benefactor, defile his conscience, and sin against God. Such conduct is so exceedingly rare that his example has stood on the records of time as almost without a parallel, admired by all, applauded by most, and in similar circumstances, I am afraid, imitated by few. The fable of the brave and virtuous Bellerophon and Sthenobaea, wife of Proetus, king of the Argives, was probably founded on this history.
3. Joseph fled and got him out. To know when to fight and when to fly are of great importance in the Christian life. Some temptations must be manfully met, resisted, and thus overcome; from others we must fly. He who stands to contend or reason, especially in such a case as that mentioned here, is infallibly ruined. Principiis obsta, "resist the first overtures of sin," is a good maxim. After-remedies come too late.
4. A woman of the spirit of Potiphar's wife is capable of any species of evil. When she could not get her wicked ends answered, she began to accuse. This is precisely Satan's custom: he first tempts men to sin, and then accuses them as having committed it, even where the temptation has been faithfully and perseveringly resisted! By this means he can trouble a tender conscience, and weaken faith by bringing confusion into the mind. Thus the inexperienced especially are often distracted and cast down; hence Satan is properly called the accuser of the brethren, Revelation 12:10.
Very useful lessons may be drawn from every part of the relation in this chapter, but detailing the facts and reasoning upon them would be more likely to produce than prevent the evil. An account of this kind cannot be touched with too gentle a hand. Others have been profuse here; I chose to be parsimonious, for reasons which the intelligent reader will feel as well as myself. Let this remark be applied to what has been said on the sin of Onan, Genesis 38.

And the Lord was with Joseph,.... Comforting him with his presence under his afflictions; supporting him with his right hand; sanctifying all his troubles to him, and so causing him to bear them patiently and cheerfully:
and showed him mercy, and gave him favour in the sight of the keeper of the prison; who was the underkeeper to Potiphar; God so wrought upon the heart of this man, that he was merciful to him, and took off the iron fetters, which hurt his feet, and gave him liberty to walk about; and many other favours and kindnesses he showed unto him, as follow.

The Lord . . . gave him favour in the sight of the keeper of the prison, &c.--It is highly probable, from the situation of this prison (Genesis 40:3), that the keeper might have been previously acquainted with Joseph and have had access to know his innocence of the crime laid to his charge, as well as with all the high integrity of his character. That may partly account for his showing so much kindness and confidence to his prisoner. But there was a higher influence at work; for "the Lord was with Joseph, and that which he did, the Lord made it to prosper."

In the prison itself Jehovah was with Joseph, procuring him favour in the eyes of the governor of the prison, so that he entrusted all the prisoners to his care, leaving everything that they had to do, to be done through him, and not troubling himself about anything that was in his hand, i.e., was committed to him, because Jehovah made all that he did to prosper. "The keeper" was the governor of the prison, or superintendent of the gaolers, and was under Potiphar, the captain of the trabantes and chief of the executioners (Genesis 37:36).

But the Lord was with Joseph and shewed him mercy. God despiseth not his prisoners, Psalm 69:33. No gates nor bars can shut out his gracious presence from his people. God gave him favour in the sight of the keeper of the prison - God can raise up friends for his people even where they little expect them. The keeper saw that God was with him, and that every thing prospered under his hand, and therefore intrusted him with the management of the affairs of the prison.
