'Behind' in the Bible

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."

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.

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."
