ISB ~ Matthew 24 v31

angels:Presumably the angels of heaven, who will accompany Christ when he comes again in his kingdom (16:27; 2 Thess 1:7). Others see them as preachers of the gospel since the Greek angeloi can also refer to human “messengers” (e.g., John the Baptist in 11:10).

trumpet call:An allusion to Is 27:13.

• Isaiah envisions the messianic restoration of Israel. Summoned by the Lord’s trumpet, the tribes of Jacob will come forth from their exile among the nations to be united with God once again.

the four winds:The four points of the compass.

• The statement recalls OT passages about the ingathering of God’s people from among the nations (Deut 30:4; Is 11:12; Zech 2:6).
