4 Bible Verses about Speaking With The Mouth

"Their mouth is full of cursing and bitterness."

After there had been much debate, Peter stood up and said to them, "Brethren, you know that in the early days God made a choice among you, that by my mouth the Gentiles would hear the word of the gospel and believe.

But what does it say? "The word is near you, in your mouth and in your heart" (that is, the word of faith which we preach);

For man believes with his heart and so is justified, and he confesses with his mouth and so is saved.
