4 Bible Verses about Speaking With The Mouth

Whose mouth is full of cursing and bitterness;

And after much debate, Peter rose up and said to them, Brethren, ye know, that God long ago made choice among us, that the Gentiles should by my mouth hear the word of the gospel and believe.

(that is, to bring Christ again from the dead) But what saith he? The word is nigh thee, even in thy mouth, and in thy heart; that is, the word of faith which we preach:

For with the heart man believeth to righteousness, and with the mouth confession is made to salvation.
