The Great Childhood Deeds of our Lord and Saviour Jesus Christ

1 1 When the boy Jesus was five years old, he was playing at the ford of a rushing stream. And he gathered the disturbed water into pools and made them pure and excellent, commanding them by the character of his word alone and not by means of a deed.

2 Then, taking soft clay from the mud, he formed twelve sparrows. It was the Sabbath when he did these things, and many children were with him.

3 And a certain Jew, seeing the boy Jesus with the other children doing these things, went to his father Joseph and falsely accused the boy Jesus, saying that, on the Sabbath he made clay, which is not lawful, and fashioned twelve sparrows.

4 And Joseph came and rebuked him, saying, “Why are you doing these things on the Sabbath?” But Jesus, clapping his hands, commanded the birds with a shout in front of everyone and said, “Go, take flight, and remember me, living ones.” And the sparrows, taking flight, went away squawking.

5 When the Pharisee saw this he was amazed and reported it to all his friends.

2 1 And the son of Annas the scribe had come with Joseph. And taking a willow twig, he destroyed the pools and drained out the water which Jesus had gathered together. And he dried up their gatherings.

2 And Jesus, seeing what had happened, said to him, “Your fruit (shall be) without root and your shoot shall be dried up like a branch scorched by a strong wind.”

3 And instantly that child withered.

3 1 While he was going from there with his father Joseph, a child running tore into his shoulder. And Jesus said to him, “You shall no longer go our way.” And instantly he died. At once the people, seeing that he was dead, cried out and said, “Where was this boy born that his word becomes a deed?”

2 When they saw what had happened the parents of the dead boy blamed his father Joseph, saying, “Because you have this boy you cannot live with us in this village. If you wish to be here, teach him to bless and not to curse.”
