no physician heals those who know him

 (30) Jesus said, "Where there are three gods, they are gods. Where there are two or one, I am with him." (31) Jesus said, "No prophet is accepted in his own village; no physician heals those who know him." (32) Jesus said, "A city being built on a high mountain and fortified cannot fall, nor can it be hidden." (33) Jesus said, "Preach from your housetops that which you will hear in your ear. For no one lights a lamp and puts it under a bushel, nor does he put it in a hidden place, but rather he sets it on a lamp stand so that everyone who enters and leaves will see its light."
