He that hath no hony in his pot, let him have it in his mouth.
Who hath bitter in his mouth, spits not all sweet.
The wise hand doth not all that the foolish mouth speakes. [The wise hand doth not all that the foolish mouth speaks.]
The ill that comes out of our mouth falles into our bosome.
One mouth doth nothing without another.
Into a mouth shut flies flie not.
In the mouth of a bad dog fals often a good bone.
