Mark 13:24-27 (HCSB)
24 “But in those days, after that tribulation:
The sun will be darkened,
and the moon will not shed its light;
25 the stars will be falling from the sky,
and the celestial powers will be shaken.
26 Then they will see the Son of Man coming in clouds with great power and glory. 27 He will send out the angels and gather His elect from the four winds, from the end of the earth to the end of the sky.
