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.
(de Cons. Ev. ii. 19.) Or He may be thought to have sought to shun the thickest crowd, and to have ascended the mountain that He might speak to His disciples alone.
