Jesus followed Moses law concerning Passover. He literally fulfilled Passover in the flesh.
He rode into Jerusalem on Nisan 10. Nisan 10 is the day the Jews pick their Passover Lambs. It can fall on any day of the week, but was a Sunday the year Jesus went to the cross.
Jesus stayed in Jerusalem, “the house of Israel” four days, and was crucified on the fourth. The Passover Lamb is kept in the home of the Jew for four days to be examined, and killed on Nisan 14, the “day of preparation”, one must also be aware that part of a day is counted as a full day to the Jew. Nisan 15 is Passover, it is reckoned by the moon, and a is a full moon Sabbath day no matter what day it falls on. This puts Jesus being crucified on Nisan 14, the day before passover that year, which had to have been a Thursday, the “day of preparation”, on which the Jews kill the Passover Lamb, and with Passover falling on a Friday that year. Another thing to remember is that Passover is a special Sabbath, no matter what day it falls on,
This would have fulfilled Moses Law of the Passover, and Jesus own prophecy about 3 days and 3 nights in the heart of the earth. The empty tomb on Sunday morning,counting the partial day of thursday afternoon, would have been three days, and three nights.
The first Sunday after passover is the first day of the feast of firstfruits. The darkness on the the day of the crucifixion was not an eclipse either. An eclipse of the sun is impossible on a full moon.
