'Grave' in the Bible

For there is not [anything] reliable in his mouth; their inner part [is] destruction. Their throat is an open grave; [with] their tongue they speak deceit.

for you will not abandon my soul to Sheol; you will not give your faithful one to see [the] grave.

set free among the dead, like [the] slain lying in [the] grave, whom you no longer remember, even those cut off from your hand.

Is your loyal love told in the grave, [or] your faithfulness in the underworld?
