“Then she runneth, and cometh to Simon Peter, and to the other disciple, whom Jesus loved, and saith unto them, They have taken away the Lord out of the sepulchre, and we know not where they have laid him.”
John 20:2 — Greek Interlinear
Church Fathers on John 20:2
The Sabbath being now over, during which it was unlawful to be there, Mary Magdalene could rest no longer, but came very early in the morning, to seek consolation at the grave: The first day of the week comes Mary Magdalene early, when it was yet dark, to the sepulcher.
Mary Magdalene, undoubtedly the most fervent in love, of all the women that ministered to our Lord; so that John deservedly mentions her only, and says nothing of the others who were with her, as we know from the other Evangelists.
Una sabbati, i.e. one day after the sabbath.
