What follows is a proven later addition.

Obviously, after calming down the women reported to the disciples. Perhaps around Tuesday. The reference above, they told no one, suggests a delay.

At this point in history, the attitude to women was pretty awful. The fact that 3 women are credited with finding the empty tomb is truly astonishing, and proves the accuracy of their report.
You will have noticed that Mark does not mention the 30 pieces of silver, or the suicide of Judas.

These details were added in later Gospels.

There is however, a strong Hebrew tradition that he committed suicide out of remorse. It also states that a potter’s field was bought with the 30 pieces of silver. It could not be returned to the Temple treasury.

Why John Mark does not say this is unclear. It is possible that he knew nothing of it.
