And for Hebrews sunset was not only the end of the previous day, but the beginning of the next day. Since the resurrection of Christ was depicted in the Feast of First Fruits, and the first fruits were offered on the first day of the week, it follows that Christ arose sometime between sunset on Saturday and 3 a.m. on Sunday. He was not in the tomb between 3 a.m. and 6 a.m. (or sunrise) according to the Gospels: And very early in the morning the first day of the week, they came unto the sepulchre at the rising of the sun. (Mk 16:2)
He rose prior to Sunday morning according to the verse. At that point look to other sections of scripture to understand the timing. What do the scriptures say in all relevant, scrptures?
1. 3 days and 3 nights was the sign of being the Messiah.
2. Hurry to bury him before sunset since a high day Sabbath started at sunset.
3. Tomb empty Sunday morning.
With the above facts then the following sequence is what has to have happened.
1. He rose just before sunset (3 days and 3 nights).
2. The day would be Saturday just before sunset.
3. Counting backwards he was buried Wednesday afternoon preparation day for the high day Sabbath.
4. In tomb Thursday through Saturday rising that afternoon.
