Ruth 2:2

2:2 One day Ruth the Moabite said to Naomi, “Let me go to the fields so I can gather grain behind whoever permits me to do so.” Naomi replied, “You may go, my daughter.”

Ruth 2:7-8

2:7 She asked, ‘May I follow the harvesters and gather grain among the bundles?’ Since she arrived she has been working hard from this morning until now – except for sitting in the resting hut a short time.”

2:8 So Boaz said to Ruth, “Listen carefully, my dear! Do not leave to gather grain in another field. You need not go beyond the limits of this field. You may go along beside my female workers.
