Charles Ellicott Commentary Mark 16:2

"And very early on the first day of the week, they come to the tomb when the sun was risen." — Mark 16:2 (ASV)

At the rising of the sun.—Literally, when the sun had risen. There seems at first a slight discrepancy between this and Matthew’s while it was yet dark. A morning haze, however, or the partial continuance of the gloom which had shrouded the city on the previous day, may well be thought of as harmonizing the two accounts.
