Whom are you mocking? At whom do you sneer and stick out your tongue? Are you not a brood of rebels, the offspring of liars?
NIV
Against whom do you make sport and take your delight? Against whom do you open wide your mouth and put out your tongue? Are you not yourselves the children of transgression, the offspring of deceit--
AMP
Against whom do ye sport yourselves? against whom make ye a wide mouth, and draw out the tongue? are ye not children of transgression, a seed of falsehood.
KJV
