O death, where is thy sting? O grave, where is thy victory?
Is it possible Jesus was resurrected on the Sabbath? The interlinear makes it look that way.
Matthew 28:1 From the eve of the sabbaths to the morning of one of the sabbaths came Mary Magdalene and the other Mary to see the tomb.
Genesis 1:5 And God is calling light, day and darkness, he calls night. And evening passes and morning passes, day one.
Leviticus 23:15-16 And you shall start to count from the morrow of the sabbath from the day you brought the omer of the wave offering. Seven complete sabbaths shall go by. From the morrow of the seventh sabbath you shall count to the 50th day and then you shall bring a new presence offering to Yahweh.
The morning after the sabbath is still the same day to a Hebrew. God counts the days of Genesis, evening and morning; first day.
That would make pentecost on the eighth sabbath, which that year could have been called Greek Sunday, by the time the sun came up. Not actually called Sunday till the fourth century. I'm not even sure the Romans were completely sold on the seven day week yet.
