'Gravestone' in the Bible

Then he said, "What [is] this gravestone that I [am] seeing?" The men of the city said to him, "[This is the] tomb of the man of God who came from Judah and proclaimed these things which you have done against the altar of Bethel."

Set up a gravestone for Moab, for it will certainly be laid in ruins! Its cities will be laid waste and become uninhabited."
