John Gill Commentary Mark 16:6

"And he saith unto them, Be not amazed: ye seek Jesus, the Nazarene, who hath been crucified: he is risen; he is not here: behold, the place where they laid him!" — Mark 16:6 (ASV)

And he says to them, be not afraid
(See Gill on Matthew 28:5), (See Gill on Matthew 28:6), where the same things, and almost in the same words, are said here.
