Later on, after 40 days:

The texts:
2 Thessalonians 2:1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,
Paul refers to the second Advent of Jesus Christ when he says “by the coming of our Lord Jesus Christ” and further by adding, “and [by] our gathering together unto him”, which are similar to the passages of 1 Thessalonians 4:13-18 [see also Matthew 24:31; Mark 13:27]:
Isaiah 11:12 And he shall set up an ensign for the nations, and shall assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth.
1 Thessalonians 4:13 But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope.
1 Thessalonians 4:14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.
Compare:
1 Corinthians 15:20 But now is Christ risen from the dead, and become the firstfruits of them that slept.
1 Corinthians 15:23 But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming.
1 Thessalonians 4:15 For this we say unto you by the word of the Lord, that we which are alive [and] remain unto the coming of the Lord shall not prevent them which are asleep.
1 Thessalonians 4:16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
1 Thessalonians 4:17 Then we which are alive [and] remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
1 Thessalonians 4:18 Wherefore comfort one another with these words.
The King James English word “coming” is translated from [G3952], “παρουσία”, “parousia”.and may be seen in many other passages [see also 1 Corinthians 16:17; 2 Corinthians 7:6-7, 10:10; Philippians 1:26, 2:12 KJB]:

Matthew 24:27 For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be.

2 Thessalonians 2:9 Even him, whose coming is after the working of Satan with all power and signs and lying wonders,
James 5:7 Be patient therefore, brethren, unto the coming of the Lord. Behold, the husbandman waiteth for the precious fruit of the earth, and hath long patience for it, until he receive the early and latter rain.
