Not true. Three days from the burial, not the arrest not even the death. ....
This is the mistake of all Thurdayers and Wednesdayers. Cleopas included the crucifixion in the timeline, as did all the NT writers. Look at what he said and look at what he included in the timeline.
Luke 24:20 The chief priests and our rulers handed him over to be sentenced to death, and they crucified him; 21 but we had hoped that he was the one who was going to redeem Israel. And what is more, it is the third day since all this took place.
Sunday was the third day, not just since the burial, but since the handing over, the sentencing and the crucifixion. They are all included, and burial is not even mentioned. Case closed.
Your'e stumbling on the term "heart of the earth" which does not mean burial. "Under the earth" was the term used for that. "Heart of the earth" is a phrase you should do some further study on.
