Rabbi Tanḥum bar Ḥiyya interpreted the verse regarding the indigent and the wealthy. On the day of another’s good fortune, rejoice with him. “On a day of misfortune, see,” see how [ you can] support the indigent, such that you will receive reward due to them. This is what Rabbi Tanḥum would do: If he was accustomed to purchase a litra of meat, he would purchase two, one for his portion and one for the indigent; [similarly, he would purchase] two bunches of vegetables, one for him and one for the indigent. “[God made] this as well as that,” these are the wealthy and the indigent, so that each will benefit from the other.112The indigent benefit from charity in this world, and the wealthy in the World to come.
Longing for Messiah
