Jesus having come to the age of thirty years, as he himself said unto me, went up to Mount Olives with his mother to gather olives. Then at midday as he was praying, when he came to these words: 'Lord, with mercy...,' he was surrounded by an exceeding bright light and by an infinite multitude of angels, who were saying: 'Blessed be God.' The angel Gabriel presented to him as it were a shining mirror, a book, which descended into the heart of Jesus, in which he had knowledge of what God hath done and what hath said and what God willeth insomuch that everything was laid bare and open to him; as he said unto me: 'Believe, Barnabas, that I know every prophet with every prophecy, insomuch that whatever I say the whole hath come forth from that book.'
Jesus, having received this vision, and knowing that he was a prophet sent to the house of Israel, revealed all to Mary his mother, telling her that he needs must suffer great persecution for the honour of God, and that he could not any longer abide with her to serve her. Whereupon, having heard this, Mary answered: 'Son, ere thou wast born all was announced to me; wherefore blessed be the holy name of God.' Jesus departed therefore that day from his mother to attend to his prophetic office.
