'Grave' in the Bible

“Their throat is an open grave;They [habitually] deceive with their tongues.”“The venom of asps is beneath their lips.”

And not only this, but we too, who have the first fruits of the Spirit [a joyful indication of the blessings to come], even we groan inwardly, as we wait eagerly for [the sign of] our adoption as sons—the redemption and transformation of our body [at the resurrection].
