'Tombs' in the Bible

And when He came out onto the land, He was met by a man from the city who was possessed with demons; and who had not put on any clothing for a long time, and was not living in a house, but in the tombs.

Woe to you! For you are like concealed tombs, and the people who walk over them are unaware of it.”

Woe to you! For you build the tombs of the prophets, and it was your fathers who killed them.

So you are witnesses and approve the deeds of your fathers; because it was they who killed them, and you build their tombs.
