Ruth 2:8-9
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.
2:9 Take note of the field where the men are harvesting and follow behind with the female workers. I will tell the men to leave you alone. When you are thirsty, you may go to the water jars and drink some of the water the servants draw.”
