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.
