'Lips' in the Bible

Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips:

But what does it say? “The word is near you, in your mouth and in your heart”—that is, the word [the message, the basis] of faith which we preach—

because if you acknowledge and confess with your mouth that Jesus is Lord [recognizing His power, authority, and majesty as God], and believe in your heart that God raised Him from the dead, you will be saved.

So faith comes from hearing [what is told], and what is heard comes by the [preaching of the] message concerning Christ.
