But the LORD was with Joseph, and showed him mercy, and gave him favor in the sight of the keeper of the prison.
All Commentaries on Genesis 39:21 Go To Genesis 39
Caesarius of Arles
AD 542
While his case was unheard, Joseph was thrown into prison as if guilty of a crime, but the Lord did not desert him there. It is not a source of shame for the innocent when they are attacked by false charges and cast into prison because justice is crushed; the Lord visits his own even in prison, and therefore there is more help where the danger is greater. What wonder is it that Christ visits his own who are in prison, when he recalls that he has been locked up in prison in the person of his people? As you have it written: “I was in prison, and you did not come to me.” Where does the divine mercy not penetrate? Joseph found such favor that he who had been shut up in prison rather guarded the bars of the prison.
