Ruth 2:7

and she said, I pray you, let me glean and gather after the reapers among the sheaves; so she came and hath continued even from the morning until now, that she tarried a little in the house, she had not even taken time to rest, so busy had she been. So the overseer praised both the humility and the diligence of Ruth, including the propriety and the reserve of her demeanor. It appears, then, that Boaz freely permitted the poor to glean on his fields, and that his overseer had taken his cue from his master, feeling very kindly disposed toward those in need, especially if they were, as in this case, humble and respectful.
