Actually, the TEXT itself shows that: "He SHALL SEND His angels... and THEY shall gather His elect from the four winds..." (i.e. from where they had been "SCATTERED") - Matthew 24:31 https://biblehub.com/matthew/24-31.htm
[at the same "GREAT" trumpet referred to in Isaiah 27:[9]12-13]
[at the same "GREAT" trumpet referred to in Isaiah 27:[9]12-13]
By the word of the Lord, we declare to you that we who are alive and remain until the coming of the Lord will by no means precede those who have fallen asleep. For the Lord Himself will descend from heaven with a loud command,
with the voice of an archangel, and with the trumpet of God, and the dead in Christ will be the first to rise.
After that, we who are alive and remain will be caught up together with them in the clouds to meet the Lord in the air. And so we will always be with the Lord.
Yeah, the LORD gives the command for His gathering of the Saints together in Him.
And again, when God brings His firstborn into the world, He says:
“Let all God’s angels worship Him.”
Yeah, those angels obey the LORD and HE will send them for His gathering - make no mistake about it.
