Romans 3:14

14 "WHOSE MOUTH IS FULL OF CURSING AND BITTERNESS ";

Romans 3:19

19 Now we know that whatever the Law says, it speaks to those who are under the Law, so that every mouth may be closed and all the world may become accountable to God;

Romans 10:8-10

8 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 are preaching,

9 that if you confess with your mouth Jesus as Lord , and believe in your heart that God raised Him from the dead, you will be saved;

10 for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.

Romans 15:6

6 so that with one accord you may with one voice glorify the God and Father of our Lord Jesus Christ.
