Mary fed by an angel

Protoev. James 8
And Mary was in the temple of the Lord as if she were a dove that dwelt there, and she received food from the hand of an angel.

Pseudo Matthew 6: 2 and 4; also 10: 2
She did not retire from praying until there appeared to her the angel of the Lord, from whose hand she used to receive food; and thus she became more and more perfect in the work of God. ...She refreshed herself only with the food which she daily received from the hand of the angel....daily do the angels of God speak with her; daily does she receive food from the hand of the Lord.

Mary at her studies

Pseudo Matthew 6: 2
No one more learned in the wisdom of the law of God ... She was always engaged in prayer and in searching the law. ...
