TSK · Leviticus 19:9

And when ye reap the harvest of your land, thou shalt not wholly reap the corners of thy field, neither shalt thou gather the gleaning of thy harvest: thou shalt leave them for the poor, and for the sojourner: I am Jehovah your God.

When thou reapest thy harvest in thy field, and hast forgot a sheaf in the field, thou shalt not go again to fetch it: it shall be for the sojourner, for the fatherless, and for the widow; that Jehovah thy God may bless thee in all the work of thy hands.

And Ruth the Moabitess said unto Naomi, Let me now go to the field, and glean among the ears of grain after him in whose sight I shall find favor. And she said unto her, Go, my daughter.

And when she was risen up to glean, Boaz commanded his young men, saying, Let her glean even among the sheaves, and reproach her not.
