Rabbi Judah ben Bezalel Lowe, known as the Maharal of Prague was famous among Jews and non-Jews alike. He was a mystic who was revered for his holiness and Torah scholarship, as well as his proficiency in mathematics, astronomy, and other sciences. Eventually, word of his greatness reached the ears of Emperor Rudolph II.
The Emperor invited the Maharal to his castle on February 23, 1592. There they conversed for one and a half hours, and developed a mutual respect for each other.
Rabbi Judah Lowe made use of his excellent connections with the Emperor, often intervening on behalf of his community when it was threatened by anti-Semitic attacks or oppression.
G‑d is always with the oppressed. Even if the oppressor is righteous and the oppressed is wicked, our sages tell us, G‑d is with the oppressed. (Lev. Rabba 27:5)
Visit the prisoners and bring them some happiness. Even if they are guilty; even if, in your eyes, they deserve whatever misery they have. Sit with them, as one of them. Treat them with respect. Bring them joy, and you will find joy there with them.
In that uplifted spirit you will bring them, they will feel human again. They will begin to feel that, if they will only so desire, they could live as a human being was meant to live, in the image of their Maker.
And then there will no longer be any need for the walls of this prison.
