Ruth 2:9

let thine eyes be on the field that they do reap, right behind the binders, where the gleaning would be most productive, and go thou after them. Have I not charged the young men that they shall not touch thee? For they may occasionally have indulged in some rudeness toward the poor gleaners. And when thou art athirst, go unto the vessels, placed there for the use of the workmen, and drink of that which the young men have drawn. Although Boaz was undoubtedly aware of a certain relationship between himself and this poor woman, he practices no condescension, he assumes no patronizing air, but protects her interests in a manner which would not hurt.
