'Mutter' in the Bible

Nor do they mutter through their throat, Like them are their makers, Every one who is trusting in them.

And when they say unto you, 'Seek unto those having familiar spirits, And unto wizards, who chatter and mutter, Doth not a people seek unto its God? -- For the living unto the dead!

For your hands have been polluted with blood, And your fingers with iniquity, Your lips have spoken falsehood, Your tongue perverseness doth mutter.
