There is no provision in the scriptures for eating Passover a day early.
However, a light
Passover
meal on the 14th is certainly permissible. That's why the "Last Supper" couldn't have been what today is a combined Passover/Unleavened Seder meal (with matzah) which many celebrate on the 14th, thereby moving up the Feast of Unleavened Bread (Leviticus 23:6), and a Passover/Unleavened Seder Service from the 15th to the 14th.
Lulav may be considering the possibility that the "Last Supper" occurred on the evening of the 14th when the original "Passover" of the Death Angel occurred at mid-night on Abib 14. Leviticus 23:5-6 states that Passover occurred on the 14th, and the Feast of Unleavened Bread was on the 15th.
Accordingly, Lulav's reasoning may be open to the possibility that the "Last Supper" was during the first few hours of the 14th. The same was true as the eating of the lambs in Egypt was on the 14th,
before the Death Angel came at mid-night on Abib 14 (Exodus 12:21-22).
The lamb is to be kept until the 14th and killed in the evening (end of the day).
The verse
doesn't say "and killed in the evening" (end of day). If that was the case then the verse would have said, "until the 15th." Look up the meaning of "until" and you'll find it means the lambs could actually be killed during the 14th (e.g. afternoon), and eaten during the beginning of the Feast of Unleavened Bread on the 15th.
That makes the Passover meal happening on the 15th day, which is the first day of unleavened bread.
Ahhhh, but during the time of Yeshua a light
Passover meal was on the 14th as the Feast of Unleavened Bread w/roasted lamb didn't begin until the 15th. But you already knew that
Did you not read the title in full?
Wine and Singing the proof that the Last Supper was the Passover
The problem, if there is a problem, is that Lulav apparently doesn't think it necessary to include Unleavened Bread as proof that the Last Supper was the
Passover meal. In fact she may be correct as during the time of Yeshua a meager
Passover meal on the 14th did not include roasted lamb or matzah which wasn't eaten until the 15th. It would not be wrong to refer to Yeshua's Last Supper as a
Passover meal on the 14th, before the Feast of Unleavened Bread on the 15th.
Therefore, what proof does one really need if they chose to believe that the Last Supper was a light
Passover meal that included: Wine, Bread w/soup and Singing. If there is a problem it may be with Messianics that believe Yeshua's
Passover meal has to conform to the 'order' of today's Passover Seder Service. Lulav has never said the "Last Supper" was a traditional Passover Seder Service as she has not included "Unleavened Bread" in her introductory sentence ...
Wine and Singing the proof that the Last Supper was the Passover
( Lulav didn't say Passover Seder ... just Passover )
