[Exodus 12:6] And it hath become a charge to you, until the fourteenth day of this month, and the whole assembly of the company of Israel have slaughtered it between the evenings.
Another confusing Hebrew term. They had "Two" evenings each day....one at high noon and the other at sunset. Between the evenings would be about 3:00 P.M. in the afternoon....the same time Our Saviour was slaughtered.
This is a good study which clears up most of these questions.
Very interesting and informative link. But it raises this question: Who kept the Passover at its proper time on Nissan 14th, 30 AD: Jesus and his Apostles at the beginning of that 14th day or the Jews and their leaders at the end of that 14th day?
