Remigius of Auxerre
Catena Aurea · Matthäusevangelium 5
Mt 5, Verses 1–3English original
And seeing the multitudes, He went up into a mountain: and when He was set, His disciples came unto Him. And He opened His mouth, and taught them, saying, Blessed are the poor in spirit: for theirs is the kingdom of heaven.
This should be known, that the Lord had three places of retirement that we read of, the ship, the mountain, and the desert; to one of these He was wont to withdraw whenever He was pressed by the multitude.
