'Message' in the Bible

Whoever does not welcome you, nor listen to your message, as you leave that house or city, shake the dust [of it] off your feet [in contempt, breaking all ties].

Now when John [the Baptist] in prison heard about the activities of Christ, he sent word by his disciples

While he was seated on the judgment seat, his wife sent him a message, saying, “Have nothing to do with that righteous and innocent Man; for last night I suffered greatly in a dream because of Him.”
