Ruth 2:2-3

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.” 2:3 So Ruth went and gathered grain in the fields behind the harvesters. Now she just happened to end up in the portion of the field belonging to Boaz, who was from the clan of Elimelech.

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.

2:23 So Ruth worked beside Boaz’s female servants, gathering grain until the end of the barley harvest as well as the wheat harvest. After that she stayed home with her mother-in-law.
