'On the First Day of the Week' in the Bible

Now Jesus being risen early on the first day of the week appeared first to Mary Magdalene, from whom He had cast out seven devils:

And on the first day of the week, very early in the morning, they came to the sepulchre, bringing the spices which they had prepared; (and some others with them:) and found the stone rolled away from the sepulchre:

Now on the first day of the week Mary Magdalene cometh early in the morning, while it was yet dark, to the sepulchre, and seeth the stone taken away from the sepulchre.

And upon the first day of the week, when the disciples were assembled together to break bread, Paul being about to depart on the morrow, preached unto them, and continued his discourse till midnight.

Upon the first day of the week let every one of you set apart something, putting it into the treasury, according as he is prospered: that there may be no need of collections, when I come.
