“The children of Israel did so, and sent them outside the camp. As the Lord spoke to Moses, so the children of Israel did” (Numbers 5:4). “The children of Israel did so, and sent them outside the camp” – to inform of the praiseworthiness of Israel that just as Moses said to them, so they did. “As the Lord spoke to Moses, so the children of Israel did” – Rabbi Elazar ben Rabbi Shimon says: This indicates only that the senders did not require [compulsion]. From where is it derived that those who were sent out also did not require [compulsion]? The verse states: “As the Lord spoke to Moses, so the children of Israel did” – of their own volition, and they did not require that Moses and Aaron would compel them.
