1. Mose 39:19

Joseph in Prison. - Potiphar was enraged at what he heard, and put Joseph into the prison where (אשׁר for שׁם אשׁר, Gen 40:3 like Gen 35:13) the king's prisoners (state-prisoners) were confined. הסּהר בּית: lit., the house of enclosure, from סהר, to surround or enclose (ὀχύρωμα, lxx); the state-prison surrounded by a wall. This was a very moderate punishment. For according to Diod. Sic. (i. 78) the laws of the Egyptians were πικροὶ περὶ τῶν γυναιῶν νόμοι. An attempt at adultery was to be punished with 1000 blows, and rape upon a free woman still more severely. It is possible that Potiphar was not fully convinced of his wife's chastity, and therefore did not place unlimited credence in what she said. (Note: Credibile est aliquod fuisse indicium, quo Josephum innocentem esse Potiphari constiteret; neque enim servi vita tanti erat ut ei parceretur in tam gravi delicto. Sed licet innocuum, in carcere tamen detinebat, ut uxoris honori et suo consuleret (Clericus). The chastity of Egyptian women has been in bad repute from time immemorial (Diod. Sic. i. 59; Herod. ii. 111). Even in the middle ages the Fatimite Hakim thought it necessary to adopt severe measures against their immorality (Bar-Hebraei, chron. p. 217), and at the present day, according to Burckhardt (arab. Sprichwrter, pp. 222, 227), chastity is "a great rarity" among women of every rank in Cairo.) But even in that case it was the mercy of the faithful covenant God, which now as before (Gen 37:20.) rescued Joseph's life.

Here is, 1. Joseph wronged by his master. He believed the accusation, and either Joseph durst not make his defence by telling the truth, as it would reflect too much upon his mistress, or his master would not hear it, or would not believe it, and there is no remedy, he is condemned to perpetual imprisonment, Gen 39:19, Gen 39:20. God restrained his wrath, else he had put him to death; and that wrath which imprisoned him God made to turn to his praise, in order to which Providence so disposed that he should be shut up among the king's prisoners, the state-prisoners. Potiphar, it is likely, chose that prison because it was the worst; for there the iron entered into the soul (Psa 105:18), but God designed to pave the way to his enlargement. He was committed to the king's prison, that he might thence be preferred to the king's person. Note, Many an action of false imprisonment will, in the great day, be found to lie against the enemies and persecutors of God's people. Our Lord Jesus, like Joseph here, was bound, and numbered with the transgressors. 2. Joseph owned and righted by his God, who is, and will be, the just and powerful patron of oppressed innocence. Joseph was at a distance from all his friends and relations, had not them with him to comfort him, or to minister to him, or to mediate for him; but the Lord was with Joseph, and showed him mercy, Gen 39:21. Note, (1.) God despises not his prisoners, Psa 69:33. No gates nor bars can shut out his gracious presence from his people; for he has promised that he will never leave them. (2.) Those that have a good conscience in a prison have a good God there. Integrity and uprightness qualify us for the divine favour, wherever we are. Joseph is not long a prisoner before he becomes a little ruler even in the prison, which is…

39:19-20 This was the second time that Joseph, while faithfully doing the right thing, was thrown into bondage with his clothing used deceptively as evidence (cp. 37:23-24, 31-33).
