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.
(Hom. xv.) By not choosing His seat in the city, and the market place, but on a mountain in a desert, He has taught us to do nothing with ostentation, and to depart from crowds, above all when we are to be employed in philosophy, or in speaking of serious things.
