Romans 3:14; Romans 3:19; Romans 10:8-10; Romans 15:6
Whose mouth is full of cursing and bitterness:
Now we know that what things soever the law saith , it saith to them who are under the law: that every mouth may be stopped , and all the world may become guilty before God.
But what saith it ? The word is nigh thee, even in thy mouth, and in thy heart: that is , the word of faith, which we preach ;
That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved .
For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
That ye may with one mind and one mouth glorify God, even the Father of our Lord Jesus Christ.
