I believe there's a connection from Nisan 21 April 11/12 2023 + 2520days = Adar 1 2030 + 7 months cleaning land of dead bodies = Feast of Trumpets 2030. Explanation below 👇.

Nisan 21, the 4th Spring feast HAS NOT BEEN FULFILLED YET . How did Jesus fulfilled Nisan 21????

Nisan 14  crucifixion.

Nisan 15 Jesus burial. Numbers 28:18 In the first day shall be an holy convocation; ye shall do no manner of servile work therein:

Nisan 17 Jesus rose from the dead. First Fruits.

Nisan 21 Sacred Assembly 7th Day  NOT FULFILLED (Lev 23:6) Red Sea split on this day.

Numbers 28:25 And on the seventh day ye shall have an holy convocation; ye shall do no servile work.

  From Tishri 1 2030 Feast of Trumpets in millennium reign counting back seven months to clean the land of dead bodies. Ez39:12 The 7 months are Elul, Av, Tammuz, Sivan, Iyar, Nisan, Adar.

Adar 1, 2030 minus 2520 days = April 11/12 2023 Nisan 21. Unfulfilled Feast.

Ez43:9 Now let them put away their whoredom, and the carcases of their kings, far from me, and I will dwell in the midst of them for ever.

Rev19:18 "That ye may eat the flesh of kings"

Deut23:14 For the Lord thy God walketh in the midst of thy camp, to deliver thee, and to give up thine enemies before thee; therefore shall thy camp be holy: that he see no unclean thing in thee, and turn away from thee.
