Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 5
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.
Every man in his own trade or profession rejoices when he sees an opportunity of exercising it; the carpenter if he sees a goodly tree desires to have it to cut down to employ his skill on, and the Priest when he sees a full Church, his heart rejoices, he is glad of the occasion to teach. So the Lord seeing a great congregation of people was stirred to teach them.
