“The stars
Will be falling
From heaven.
The powers
In the heavens
Will be shaken.”
καὶ οἱ ἀστέρες ἔσονται ἐκ τοῦ οὐρανοῦ πίπτοντες, καὶ αἱ δυνάμεις αἱ ἐν τοῖς οὐρανοῖς σαλευθήσονται.
This is almost word for word in Matthew, chapter 24:29, with a vague reference to this in Luke, chapter 21:25. Mark said that the stars would fall from the skies (καὶ οἱ ἀστέρες ἔσονται ἐκ τοῦ οὐρανοῦ πίπτοντες). The powers of the heavens would be shaken or stirred up (καὶ αἱ δυνάμεις αἱ ἐν τοῖς οὐρανοῖς σαλευθήσονται) in this time of complete darkness, during this celestial disturbance. This was fully in line with the great Israelite prophetic tradition of the Day of Yahweh, like Ezekiel, chapter 32:7, Joel, chapter 2:10, Amos, chapter 8:9, and Zephaniah, chapter 1:15
