And Joseph's master took him, and put him into the prison, a place where the king's prisoners were bound: and he was there in the prison.
All Commentaries on Genesis 39:20 Go To Genesis 39
Chromatius of Aquileia
But the holy man considered that prison to be a palace; and Joseph himself was a palace in his prison, because where faith, chastity and modesty are, there the palace of Christ is, the temple of God, the dwelling of the Holy Spirit …. In the church there are three models of chastity that everybody must imitate: Joseph, Susanna and Mary. May men imitate Joseph, women Susanna and the virgin Mary.
