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 27:7)
Visit the prisoners and bring them some happiness. Even if they are guilty; even if, in your eyes, they deserve whatever misery they have. Bring them joy.
And it is not only those in the penitentiary. A hospital, a home for the elderly, even a private residence of a lonely old man—these, too, can be prisons of the soul. Purim 5736:4
