Abib barley is a stage of growth. The grain turns to a mellow green and can be parched and eaten at this stage. It is ripe and can be harvested, though the ripeness is not so much that the grain can be ground.
Why would any of this matter?
Four times the LORD said to observe the month of Abib, all with the keeping of Passover or the Feast of Unleavened bread.
Ex 13:4-5 On this day you are going out, in the month Abib. And it shall be, when the Lord brings you into the land of the Canaanites and the Hittites and the Amorites and the Hivites and the Jebusites, which He swore to your fathers to give you, a land flowing with milk and honey, that you shall keep this service in this month.
Ex 23:15 You shall keep the Feast of Unleavened Bread (you shall eat unleavened bread seven days, as I commanded you, at the time appointed in the month of Abib, for in it you came out of Egypt; none shall appear before Me empty);
Ex 34:18 The Feast of Unleavened Bread you shall keep. Seven days you shall eat unleavened bread, as I commanded you, in the appointed time of the month of Abib; for in the month of Abib you came out from Egypt.
Deut 16:1 Observe the month of Abib, and keep the Passover to the Lord your God, for in the month of Abib the Lord your God brought you out of Egypt by night.
Also a sheaf or wave offering could not happen until the barley was abib.
The Hebrews do several things different from most of the rest of us.
A new day for them starts at sunset; where as a new one for us begins at midnight.
A new month begins with the observance of a new moon; I just wait for the first on the calendar.
Most of our Western holidays are fixed – July 4th, Christmas Day, and New Years Day are all on fixed dates.
Thanksgiving is the 4th Thursday of November and Mother’s Day the 2nd Sunday of May. Easter drifts, being the first Sunday after the first full moon after the first day of Spring.
Passover may appear to drift around on our calendar but it is always begins at sundown on fourteenth day of the Jewish month of Nisan, based on a lunar calendar.
So keeping up with the phases of the moon and seasons are important.
You cannot have Passover before the first day of Spring. But it would definitely happen if the calendar was left alone.
So a watch on barley was used.
As the end of the religious calendar came to an end the search for abib took place. If enough was found to put a sickle to it, then the next new moon would usher in the month of Nisan and the next full moon would be Passover.
If the barley was not abib, then an extra [leap] month was added and the following new moon would be Nisan, some 30 days later.
So what is the barley report? I report what I have found next time.
