Ruth 2:14-17

[14] At mealtime, Boaz said to her, "Come over here and partake of the meal, and dip your morsel in the vinegar." So she sat down beside the reapers. He handed her roasted grain, and she ate her fill and had some left over. [15] When she got up again to glean, Boaz gave orders to his workers, "You are not only to let her glean among the sheaves, without interference, [16] but you must also pull some [stalks] out of the heaps and leave them for her to glean, and not scold her." [17] She gleaned in the field until evening. Then she beat out what she had gleaned - it was about an ephah of barley.
