'Grave' in the Bible

But if the Lord does something entirely new, and the earth opens its mouth and swallows them up along with all that they have, and they go down alive to the grave, then you will know that these men have despised the Lord!"

And whoever touches the body of someone killed with a sword in the open fields, or the body of someone who died of natural causes, or a human bone, or a grave, will be unclean seven days.

Then a ceremonially clean person must take hyssop, dip it in the water, and sprinkle it on the tent, on all its furnishings, and on the people who were there, or on the one who touched a bone, or one killed, or one who died, or a grave.
