Genesis 39:20

Joseph's master, &c.— Hasty and credulous, Potiphar sent Joseph into the prisons where state-criminals were kept, where he was at first severely treated; ch. Genesis 40:15. his feet were hurt with fetters, the iron entered into his soul, Psalms 105:18 and there he continued three years; yet the Almighty forsook him not; Psalms 105:21. The Lord was still with him, and, by his mysterious Providence, made his lowest disgrace the means of his greatest exaltation.
