Mark’s introduction to the narrative (9.14-16) is considerably longer than that of Matthew (17.14) or Luke (9.37).

And when they came to the crowd: since a new section begins here, it may be advisable to identify by name the persons involved: “When Jesus and his disciples returned to the crowd” or “When Jesus and his disciples came back down the mountain to where the crowd was.”

A man came up to him: Good News Translation identifies him as Jesus, though it seems better to introduce him at the beginning of this verse; however, if that is not done, then Jesus should definitely be marked by name at this point in the narrative. In some languages came up to him will more naturally be “went up to him” or “approached Jesus.”

Kneeling translates a participle dependent upon the main verb came. The receptor language will determine the particular form of these two verb forms; Good News Translation has “… came to Jesus, knelt before him.” Some translators will start a new sentence: “… approached Jesus. He knelt before Jesus and said.”
