'Chatter' in the Bible

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!

Like a crane or a swallow, so did I chatter: I did mourn as a dove: mine eyes fail with looking upward: O LORD, I am oppressed; undertake for me.
