21 25 'Portents will appear in sun, moon, and stars. On earth nations will stand helpless, not knowing which way to turn from the roar and surge of the sea; 21 26 [ Is.34.4. ] men will faint with terror at the thought of all that is coming upon the world; for the celestial powers will be shaken. 21 27 [ Dn.7.13. ] And then they will see the Son of Man coming on a cloud with great power and glory. 21 28 When all this begins to happen, stand upright and hold your heads high, because your liberation is near.'
