First generation disciples, had never proclaimed in the bible:

Jesus was risen on the first day of the week, only:

63 “Sir,” they said, “we remember that while he was still alive that deceiver said, ‘After three days I will rise again.’

32 He replied, “Go tell that fox, ‘I will keep on driving out demons and healing people today and tomorrow, and on the third day I will reach my goal.’

32 But after I have risen, I will go ahead of you into Galilee.”

24 But God raised him from the dead, freeing him from the agony of death, because it was impossible for death to keep its hold on him.

15 You killed the author of life, but God raised him from the dead. We are witnesses of this.

30 But God raised him from the dead,

40 but God raised him from the dead on the third day and caused him to be seen.

4 that he was buried, that he was raised on the third day according to the Scriptures,
