Sermon on the mount
After spending a night in solemn meditation and prayer in the
lonely mountain-range to the west of the Lake of Galilee (Luke
6:12), on the following morning our Lord called to him his
disciples, and from among them chose twelve, who were to be
henceforth trained to be his apostles (Mark 3:14, 15). After
this solemn consecration of the twelve, he descended from the
mountain-peak to a more level spot (Luke 6:17), and there he sat
down and delivered the "sermon on the mount" (Matt. 5-7; Luke
6:20-49) to the assembled multitude. The mountain here spoken of
was probably that known by the name of the "Horns of Hattin"
(Kurun Hattin), a ridge running east and west, not far from
Capernaum. It was afterwards called the "Mount of Beatitudes."
