My wife threatened to leave/kill me if I did it, but maybe yours has a better sense of humor. In case you were around for the big Nisan 14/15 debate, you might know I assert the Bible absolutely and thoroughly demonstrates the Passover falls on Nisan 15 and Nisan 14 was the "preparation day".
Tonight, at the book study, the daily sacrifice that was to be done twice a day at the temple was mentioned.
Prayers were offered at the temple in conjunction with the morning and evening sacrifices. The evening sacrifice was held at “the ninth hour,” or about three in the afternoon. - bt p28 (footnote)
This is the sacrifice:
And you will offer the one young ram in the morning, and you will offer the other young ram between the two evenings. - Exo 29:39
Notice "between the two evenings" is identified correctly as "about three in the afternoon", which agrees with:
The time "between the two evenings" ("ben ha-'arbayim") was construed to mean "after noon and until nightfall," - Jewish Encyclopedia
On the other hand, when JWs talk about Passover, they insist:
the weight of evidence points to the application of the expression “between the two evenings” to the time between sunset and dark. - it-2 p581, under "Passover"
The understanding of the book “Bearing Thorough Witness” About God’s Kingdom accurately explains "between the two evenings" as being afternoon, placing the Passover celebration squarely on 15 Nisan, not 14. To bolster their error, in typical JW fashion, they manage to dig up an "expert" who will back their idiocy and dogmatism. Jews know Passover is prepared on 14 Nisan and eaten on 15 Nisan and celebrate it that way to this day. JWs just have to pick a fight with everybody about everything, so they insist preparation and eating was crammed together immediately at the beginning of 14 Nisan. In reality, Passover was prepared during the waning hours of 14 Nisan and eaten after sundown (the next calendar day for Jews) shortly after the beginning of 15 Nisan. But just like all liars, they've spun a tangled web and their loose ends keep popping out for anyone to see, if they're willing to open their eyes.
