'Tomb' in the Bible

"Listen, sir, you are a mighty prince among us! You may bury your dead in the choicest of our tombs. None of us will refuse you his tomb to prevent you from burying your dead."

My father made me swear an oath. He said, "I am about to die. Bury me in my tomb that I dug for myself there in the land of Canaan." Now let me go and bury my father; then I will return.'"
