Hebrews 12:25-27

New Catholic Bible

²⁵ See that you do not reject the one who is speaking. For if those did not escape when they rejected the one who warned them on earth, how much more is this true of us if we turn away from the one who is from heaven? ²⁶ At that time, his voice shook the earth, but now he has promised, “Once more I will shake not only the earth but heaven as well.”

²⁷ The words “once more” indicate the removal of what can be shaken—that is, all created things—so that what cannot be shaken may remain.
