These are the things that have no measurement: The corners [of the field], The first-fruits, [The offerings brought] on appearing [at the Temple on the three pilgrimage festivals], The performance of righteous deeds, And the study of Torah.
These are precepts, the fruits of which a person enjoys in this world, while the principal reward remains for them in the World-to-Come:
Honoring one's father and mother,
Acts of kindness,
Early attendance in the House of Study morning and evening,
Providing hospitality to guests,
Visiting the sick,
Bringing a bride in [to the chupah], Escorting the dead,
Deep concentration during prayer, Bringing peace between a person and their friend, or between husband and wife — And the study of Torah is equal to them all.
