Joseph of Arimathaea had a prominent role in the burial of Jesus when Jesus didn’t seem to have much support. Interestingly, the accounts shed some light on when the Sabbath starts.
Deut 21:23 says
‘First day of the week’ translated from ‘mia ton sabbaton’ requires ‘mia’ to be rendered in a way that would not make sense in most verses that use it.
On resurrection morning, Mary came to the tomb when it was yet dark. Later the disciples met. Both were on Sabbath. Clearly, Sabbath includes both the night and the following day.
