When did the women (or woman) arrive at the sepulchre?
While it was still dark.
The first day of the week cometh Mary Magdalene early, when
it was yet dark, unto the sepulchre, and seeth the stone taken
away from the sepulchre. John 20:1
As it began to dawn toward the first day of the week,
came Mary Magdalene and the other Mary to see the sepulchre. Matthew 28:1
And when the sabbath was past, Mary Magdalene, and Mary the
mother of James, and Salome, had bought sweet spices, that they might
come and anoint him. And very early in the morning the first day of
the week, they came unto the sepulchre at the rising of the sun. Mark 16:1-2
