Just wanted to remind everyone about the 4th Spring Feast Nisan 21 is Still Unfulfilled April 29, 2024.
Only 3/4 of the Spring Feasts has been fulfilled the 4th feast HAS NOT BEEN FULFILLED YET NISAN 21 the 7th day of Unleavened Bread
On this day a sacred assembly is held. That means Nisan 21 might have a future fulfillment.

(1)Passover 14th of Nisan FULFILLED crucifixion

(2)Feast of Unleavened Bread 15th of Nisan FULFILLED. On the first day of the Feast of Unleavened Bread was the burial of Jesus.
And on the fifteenth day of the same month is the Feast of Unleavened Bread to the Lord; for seven days you shall eat unleavened bread. On the first day (Nisan 15) you shall have a holy convocation” (Lev 23:6).

(3)The feast of First Fruits 17th of Nisan. Jesus rose from the dead FULFILLED Lev23:9-11

(4)Nisan 21 Sacred Assembly 7th Day of Unleavened Bread NOT FULFILLED YET.
"On the seventh day(Nisan 21) is a holy convocation; you shall not do any ordinary work” (Lev 23:8).

Also on Nisan 21 (1313 BCE), the Red Sea split Moses and the people crossed over. Could the saints Cross over in the rapture on this day?
