'Glean' in the Bible
You shall not glean your vineyard, neither shall you gather the fallen grapes of your vineyard; you shall leave them for the poor and for the foreigner. I am Yahweh your God.
When you gather [the grapes of] your vineyard, you shall not glean it after yourselves: it shall be for the foreigner, for the fatherless, and for the widow.
Ruth the Moabitess said to Naomi, "Let me now go to the field, and glean among the ears of grain after him in whose sight I shall find favor." She said to her, "Go, my daughter."
She said, 'Please let me glean and gather after the reapers among the sheaves.' So she came, and has continued even from the morning until now, except that she stayed a little in the house."
Then Boaz said to Ruth, "Listen, my daughter. Don't go to glean in another field, and don't go from here, but stay here close to my maidens.
When she had risen up to glean, Boaz commanded his young men, saying, "Let her glean even among the sheaves, and don't reproach her.
Also pull out some for her from the bundles, and leave it, and let her glean, and don't rebuke her."
So she stayed close to the maidens of Boaz, to glean to the end of barley harvest and of wheat harvest; and she lived with her mother-in-law.
They cut their provender in the field. They glean the vineyard of the wicked.
