Psalms 5:9

For there is no truth in their mouth ; their inmost self is destruction ; their throat is an open grave ; they flatter with their tongue .

Not a word from their mouth can be trusted; their heart is filled with malice. Their throat is an open grave; with their tongues they tell lies.

For there is no faithfulness in their mouth; their inward part is very wickedness; their throat is an open sepulchre; they flatter with their tongue.
