338. Did Jesus preach his first sermon on a mountain or a plain?
On a mountain top
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... Matthew 5:1-3
On a plain
And he came down with them, and stood in the plain, and the company of his disciples, and a great multitude of people out of all Judaea
and Jerusalem, and from the sea coast of Tyre and Sidon, which came to hear him, and to be healed of their diseases; ...
And he lifted up his eyes on his disciples, and said, Blessed be ye poor: for yours is the kingdom of God... Luke 6:17, 20
