'Mouth' in the Bible

That which is gone out of thy lips thou shalt keep and perform; even a freewill offering, according as thou hast vowed unto the LORD thy God, which thou hast promised with thy mouth.

But the word is very nigh unto thee, in thy mouth, and in thy heart, that thou mayest do it.

Give ear, O ye heavens, and I will speak; and hear, O earth, the words of my mouth.
