The Sermon on the Mount appears in Matthew's Gospel, where Jesus preaches to the multitude.Matthew is not considered to have been the original source of the Sermon on the Mount material, as much of it also appears in Luke's Gospel, which has Jesus give privately to the disciples alone and not even as a discrete sermon. The source for much of the material in the Sermon on the Mount, including four of the Beatitudes, is the hypothetical 'Q' document.
The first appearance of the word "disciple" (in the KJV) is its only Old Testament appearance; in Isaiah 8:16.In the New Testament, it first appears in Matthew 5:1, as Jesus is about to begin the "Sermon on the Mount."
Jesus came first in the gospel of Matthew.
