Exodus 12:17 And ye shall observe the feast of Unleavened Bread; for in this selfsame day have I brought your armies out of the land of Egypt: therefore shall ye observe this day in your generations by an ordinance for ever.
Why Don’t We All Keep the Feasts? We are STILL commanded to keep ALL these feasts today!
For 7 days we must eat bread with no yeast and throw out all bread (consumables) with yeast. The 1st day ( and 7th day) of this feast were Sabbaths. Yahshua remained in the grave, resting on this day. (Luke 23:54-56)
It was on this day, the day after the Passover, that YHWH led Moses
and the Israelites out of bondage in Egypt.
And they baked unleavened cakes of the dough which they broughtforth out of Egypt, for it was not leavened; because they were thrust out of Egypt, and could not tarry, neither had they prepared for themselves any victual.
Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened.
For even Christ our Passover is sacrificed for us:Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth.
(1 Cor 5:7-8)
