'Grave' in the Bible

They buried Abner in Hebron: and the king lifted up his voice, and wept at the grave of Abner; and all the people wept.

David commanded his young men, and they killed them, and cut off their hands and their feet, and hanged them up beside the pool in Hebron. But they took the head of Ishbosheth, and buried it in the grave of Abner in Hebron.

Please let your servant turn back again, that I may die in my own city, by the grave of my father and my mother. But behold, your servant Chimham; let him go over with my lord the king; and do to him what shall seem good to you."
