Seeing the crowds, he goes up the hillside, sits down as a teacher does, and begins with the people nobody congratulates: the poor in spirit, those who mourn, the meek, the hungry for righteousness. What follows is not a set of rules but a description of a different kind of life, going behind murder to anger and behind adultery to the look. The crowd is astonished, because he teaches as one who has authority.
The passage
1And seeing the multitudes, he went up into a mountain: and when he was set, his disciples came unto him:
2And he opened his mouth, and taught them, saying,
3Blessed {are} the poor in spirit: for theirs is the kingdom of heaven.
4Blessed {are} they that mourn: for they shall be comforted.
5Blessed {are} the meek: for they shall inherit the earth.
Jesus sees the crowds, goes up a hillside, sits down the way a teacher would, and begins speaking to the people nobody usually congratulates, such as the poor in spirit and those who mourn. He goes on to describe a whole way of life rather than a list of rules, tracing murder back to anger and adultery back to the look that precedes it. By the end the crowd is astonished at the authority with which he teaches.
The text simply says Jesus went up the hillside, without naming the mountain, and tradition locates it near the Sea of Galilee at a rise now called the Mount of Beatitudes. The setting matters mainly because it echoes a teacher going up to instruct, with the crowd gathering below and around him. Scripture itself does not give the mountain a name or further description.
It matters because Jesus starts not with the strong or the successful but with those nobody praises, the poor in spirit, the mourning, the meek, the hungry for righteousness, turning ordinary expectations upside down. He then shows that his teaching goes deeper than outward behavior, addressing the anger behind murder and the look behind adultery. The crowd's astonishment at his authority signals that something more than ordinary teaching is happening here.
A common misreading treats it as a stricter rulebook layered on top of the old law, but what follows the opening blessings reads more as a description of a different kind of life than a checklist. Jesus pushes past outward acts to their roots, tracing murder to anger and adultery to the look that comes before it. Readers differ on how literally to apply each saying, but the passage itself frames it as character and inner orientation rather than mere regulation.
