'Grave' in the Bible

And every one that toucheth one that is slain with a sword in the open fields, or a dead person, or the bone of a man, or a grave, shall be unclean seven days.

and a clean man shall take hyssop, and dip it in the water, and sprinkle it on the tent, and upon all the utensils, and upon the persons that were there, and upon him that hath touched the bone, or the one slain, or the dead person, or the grave;
