***Have you never heard of the “Count of the Omer”?***
Of course I’ve heard of it and discussed it many times here on FR. The Feast of the First fruits was on the day AFTER the weekly Sabbath, or SUNDAY. counted seven days till the next, until you reach Pentecost which is also on SUNDAY, the day the Apostles gathered together and the Holy Spirit was poured out on them.
You know..............I don't believe I have ever encountered someone (a Protestant) who is wrong on just about everything ...............
Celebrating the First Fruits took place after the First Sabbath of Unleavened.....which wasn't always on a Saturday. The year of the crucifixion.... this High Sabbath [John 19:31] was on Wednesday night/Thursday and the First Fruits were on Thursday night/Friday.
[Josephus Antiquities; Book III; Chapter X; Paragraph X]
In the month of Xanthicus, which is by us called Nisan, and is the beginning of our year, on the fourteenth day of the lunar month, when the sun is in Aries, (for in this month it was that we were delivered from bondage under the Egyptians,) the law ordained that we should every year slay that sacrifice which I before told you we slew when we came out of Egypt, and which was called the Passover; and so we do celebrate this passover in companies, leaving nothing of what we sacrifice till the day following. The feast of unleavened bread succeeds that of the passover, and falls on the fifteenth day of the month, and continues seven days, wherein they feed on unleavened bread; on every one of which days two bulls are killed, and one ram, and seven lambs. Now these lambs are entirely burnt, besides the kid of the goats which is added to all the rest, for sins; for it is intended as a feast for the priest on every one of those days. But on the second day of unleavened bread, which is the sixteenth day of the month, they first partake of the fruits of the earth, for before that day they do not touch them. And while they suppose it proper to honor God, from whom they obtain this plentiful provision, in the first place, they offer the first-fruits of their barley, and that in the manner following: They take a handful of the ears, and dry them, then beat them small, and purge the barley from the bran; they then bring one tenth deal to the altar, to God; and, casting one handful of it upon the fire, they leave the rest for the use of the priest. And after this it is that they may publicly or privately reap their harvest. They also at this participation of the first-fruits of the earth, sacrifice a lamb, as a burnt-offering to God.
Paragraph XI: When a week of weeks has passed over after this sacrifice, (which weeks contain forty and nine days,) on the fiftieth day, which is Pentecost, but is called by the Hebrews Asartha, which signifies Pentecost, they bring to God a loaf, made of wheat flour, of two tenth deals, with leaven; and for sacrifices they bring two lambs; and when they have only presented them to God, they are made ready for supper for the priests; nor is it permitted to leave any thing of them till the day following. They also slay three bullocks for a burnt-offering, and two rams; and fourteen lambs, with two kids of the goats, for sins; nor is there anyone of the festivals but in it they offer burnt-offerings; they also allow themselves to rest on every one of them. Accordingly, the law prescribes in them all what kinds they are to sacrifice, and how they are to rest entirely, and must slay sacrifices, in order to feast upon them.
The forty nine days , of course....is the Count of the Omer and begins with the First Fruit Sacrifice on the 16th no matter which day of the week it falls on. Celebrating the first fruits on Sunday was the Sadduccee method....and quickly copied by the Catholic Church since everything else they do is wrong as well. Josephus
Pentecost, crucifixion year was on Friday, Sivan 6,30 A.D.
You can also see the three day sequence of Passover, the First Sabbath and the first Fruits happening on three successive days by reading [Joshua 5:10-12]. They couldn't eat the grain until the offering had been made and it was made on the day after the Sabbath of Unleavened. Then....the manna stopped.
