Matthew 24:29, 30, Sun will be darkened…sign of the Son of Man. Here Yeshua tells us that certain harbingers of his second coming will occur first. These include phenomenon occurring in the heavens involving the sun, moon and the stars. After this, a miraculous sign in the heavens will occur, and then Yeshua will come. Between the signs of the sun, moon and stars and the final miraculous sign of his coming there’s a gap in time. Yeshua later revealed to John that the cosmic disturbances involving the sun, moon and stars would correspond with the sixth seal (as part of the of the great tribulation that occurs before Elohim pours out his wrath on the earth) of Revelation 6:12–17. After this, Elohim pours out his wrath upon the earth (Rev 6:17; 11:18; 15:1; 16:1), and then the second advent of Yeshua occurs.
Does the sign of the Son of Man coming (Matt 24:30lp) occur before or after the wrath of Elohim? That’s hard to say, but since Yeshua states that between the two events all men will mourn, perhaps this is a veiled reference to the wrath of Elohim that is to be poured out on unregenerate men during the seven trumpets, seven thunders and seven bowl judgments described in the Book of Revelation. Why else would men be mourning? The intervening time between the cosmic disturbances (the sixth seal of Rev 6:12–17) and Yeshua’s second coming during which Elohim pours out his wrath could be a year or more, since the Scriptures speak of the day (or a period of time) of YHVH’s wrath. The Hebrew word for day (Heb. yom) can mean both a day and a period of time.
The prophet Isaiah speaks in several places about “the day of YHVH’s vengeance” (or words to this effect). This is the time period when YHVH will judge the nations including Babylon the Great, which occurs at Yeshua’s second coming (see Rev 18 and 19). In three places, Isaiah indicates that the day of YHVH will last for one year (Isa 34:8; 61:2 and 63:4). Interestingly, in Isaiah 63:4, the prophet couples the idea of the day of YHVH’s vengeance being a year long with the jubilee year—“the year of my redeemed has come.” This occurs as the Messiah (the subject of Isa 63:1–6) judges the enemies of Israel (notably Edom) as he is at the same time about to redeem (i.e. regather and return scattered Israel to its Promised Land inheritance). It appears that while Yeshua is judging Israel’s enemies at his second coming, he will at the same time be regathering the lost and scattered 12 tribes of Israel. Yeshua seems to allude to this in Matthew 24:31.
