4 Bible Verses about Speaking With The Mouth

whose mouth is full of cursing and bitterness:

When after much dispute, Peter arose, and said unto them, Men and brethren, ye know that a considerable time ago God chose among us, by my mouth, that the Gentiles should hear the gospel-word, and believe.

But what saith it? "The word is nigh thee, in thy mouth, and in thy heart:" that is, the word of faith which we preach;

For with the heart faith is exercised unto righteousness; and with the mouth is confession made unto salvation.
