Surely

"Certainly" or "There is no doubt that"

Doctor, heal yourself

If someone claims to be able to heal diseases that he himself has, there is no reason to believe he is really a doctor. People will speak this proverb to Jesus to say that they will only believe he is a prophet if they see him do what they have heard that he did in other places. (See: rc://en/ta/man/translate/writing-proverbs)

Whatever we heard ... do the same in your hometown

The people of Nazareth do not believe Jesus is a prophet because of his low status as Joseph's son. They will not believe unless they personally see him do miracles.
