“When Jesus came down
From the mountain,
Καταβάντος δὲ αὐτοῦ ἀπὸ τοῦ ὄρους ἠκολούθησαν αὐτῷ ὄχλοι πολλοί.
Just like Moses went up the mountain and came down from the mountain, Jesus went up the mountain in chapter 5:1, now he came down from the mountain (Καταβάντος δὲ αὐτοῦ ἀπὸ τοῦ ὄρους). Matthew continued to use the phrase great crowds followed or accompanied him (ἠκολούθησαν αὐτῷ ὄχλοι πολλοί). A new phase in the life of Jesus was to begin. The time of mountain teaching had ended. It was time for action.
