International Standard Version How terrible it will be for you! You are like unmarked graves—people walk on them without realizing it."
American Standard Version Woe unto you! for ye are as the tombs which appear not, and the men that walk over them know it not.
Young's Literal Translation 'Woe to you, scribes and Pharisees, hypocrites, because ye are as the unseen tombs, and the men walking above have not known.'
