Passage
And seeing the multitudes, he went up into a mountain, and when he was set down, his disciples came unto him.
And seeing the multitudes, he went up into a mountain, and when he was set down, his disciples came unto him.
Matthew 5:1 And seeing the multitudes, he went up into a mountain, and when he was set down, his disciples came unto him.
Matthew 5:2 And opening his mouth he taught them, saying:
Matthew 5:3 Blessed are the poor in spirit: for theirs is the kingdom of heaven.
The verse centers on "seeing", "multitudes", "went", "mountain", "down", "disciples", and "came". It is saying that the verse draws attention to "seeing" and "multitudes", so its meaning should be read from those terms before moving to application.
The next verse adds "And opening his mouth he taught them...", so "seeing" and "multitudes" should be read forward into that movement. In Matthew context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "seeing" and "multitudes" with trust shaped by these words, not by a vague optimism outside the passage.
