“The Son of Man

Will send out

His angels

With a loud trumpet call.

They will gather

His elect

From the four winds,

From one end

Of heaven

To the other end.”

 

καὶ ἀποστελεῖ τοὺς ἀγγέλους αὐτοῦ μετὰ σάλπιγγος μεγάλης, καὶ ἐπισυνάξουσιν τοὺς ἐκλεκτοὺς αὐτοῦ ἐκ τῶν τεσσάρων ἀνέμων ἀπ’ ἄκρων οὐρανῶν ἕως ἄκρων αὐτῶν

 

This is almost word for word, in Mark, chapter 13:27.  The Son of Man would send out his angels (καὶ ἀποστελεῖ τοὺς ἀγγέλους αὐτοῦ) with a loud or great trumpet call (μετὰ σάλπιγγος μεγάλης).  Thus, the angels were the apostles or sent ones for gathering the chosen ones.  The trumpet call was another great traditional Israelite idea to gather the people for one reason or another. These angels would gather his elect or chosen ones (μετὰ σάλπιγγος μεγάλης) from the four winds (ἐκ τῶν τεσσάρων ἀνέμων), from one end of the heavens to the other end (ἀπ’ ἄκρων οὐρανῶν ἕως ἄκρων αὐτῶν).  The Son of Man would send his apostolic angels to gather the chosen ones from all over the place.
