Here's Vines on day (hemera)
As the "day" throws light upon things that have been in darkness, the word is often associated with the passing of judgment upon circumstances. In
1Cr 4:3, "man's day," AV, "man's judgement," RV, denotes mere human judgment upon matters ("man's" translates the adjective
anthropinos, "human"), a judgment exercised in the present period of human rebellion against "God;" probably therefore "the Lord's Day,"
Rev 1:10, or "the Day of the Lord" (where an adjective,
kuriakos, is similarly used), is the Day of His manifested judgment on the world.
The phrases "the day of Christ,"
Phl 1:10;
2:16; "the day of Jesus Christ,"
Phl 1:6; "the day of the Lord Jesus,"
1Cr 5:5;
2Cr 1:14; "the day of our Lord Jesus Christ,"
1Cr 1:8, denote the time of the Parousia of Christ with His saints, subsequent to the Rapture,
1Th 4:16,
17. In
2Pe 1:19 this is spoken of simply as "the day," (see
DAY-STAR).
From these the phrase "the day of the Lord" is to be distinguished; in the OT it had reference to a time of the victorious interposition by God for the overthrow of the foes of Israel, e.g.,
Isa 2:12;
Amo 5:18; if Israel transgressed in the pride of their hearts, the Day of the Lord would be a time of darkness and judgment. For their foes, however, there would come "a great and terrible day of the Lord,"
Joe 2:31;
Mal 4:5. That period, still future, will see the complete overthrow of Gentile power and the establishment of Messiah's Kingdom,
Isa 13:9-11;
34:8;
Dan 2:34,
44;
Oba 1:15; cp.
Isa 61:2;
Jhn 8:56.
In the NT "the day of the Lord" is mentioned in
1Th 5:2;
2Th 2:2, RV, where the Apostle's warning is that the church at Thessalonica should not be deceived by thinking that "the Day of the Lord is now present." This period will not begin till the circumstances mentioned in
verses 3 and 4 take place. For the eventual development of the Divine purposes in relation to the human race see
2Pe 3:12, "the Day of God."
