'Marker' in the Bible

Jacob set up a marker over her grave; it is the Marker of Rachel's Grave to this day.

Cursed is the one who moves his neighbor's boundary marker.' Then all the people will say, 'Amen!'

He asked, "What is this grave marker I see?" The men from the city replied, "It's the grave of the prophet who came from Judah and foretold these very things you have done to the altar of Bethel."
