A.T. Robertson Commentary Matthew 28:10

"Then saith Jesus unto them, Fear not: go tell my brethren that they depart into Galilee, and there shall they see me." — Matthew 28:10 (ASV)

Fear not (μη φοβεισθε). They were still afraid for joy and embarrassment. Jesus calms their excitement by the repetition of the charge from the angel for the disciples to meet him in Galilee. There is no special mention of Peter ("and Peter") as in Mr 16:7, but we may be sure that the special message to Peter was delivered.
