Bede

Jonathan therefore gave his weapons to the boy, etc. He gave examples of the learned, he gave the rules of good conduct to be imitated by his disciples in the Church, and said to them: Go, advancing from strength to strength, compare these things with the testimonies of the law and the prophets, and see that we do nothing different under the teaching of Christ than what Moses and the prophets have spoken about the future.
