Ver. 1,2. The last chapter concluded with telling us that a great multitude followed Christ, which he observing, that he might with more convenience to himself, and advantage to them, speak what he had to say,
he went up into a mountain; and sitting down, after the manner of the Jewish doctors to show their authority, which our Saviour also at other times observed, Mat_26:55Luk_4:20Joh_8:2,
his disciples came unto him; both those strictly so called, and others also, viz. the multitude, mentioned in the last chapter, or some of them; and he began to speak to them with freedom, so as the multitude might hear. Christ thought it as lawful to preach in the mountain as in the synagogues; nor did his disciples doubt the lawfulness of hearing him, wherever he thought fit to speak.
