"Chapter 86—Go Teach All N ations This chapter is based on Matthew 28:16-20 . Standing but a step from His heavenly throne, Christ gave the commission to His disciples. “All power is given unto Me in heaven and in earth,” He said. “Go ye therefore, and teach all nations.” “Go ye into all the world, and preach the gospel to every creature.” Mark 16:15 . Again and again the words were repeated, that the disciples might grasp their significance. Upon all the inhabitants of the earth, high and low, rich and poor, was the light of heaven to shine in clear, strong rays. The disciples were to be colaborers with their Redeemer in the work of saving the world. DA 818"
"Then the eleven disciples went away into Galilee, into a mountain where Jesus had appointed them. And when they saw him, they worshipped him: but some doubted. And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen."

Ellen White directly references Mark 16:15 in this passage.
"The commission had been given to the twelve when Christ met with them in the upper chamber; but it was now to be given to a larger number. At the meeting on a mountain in Galilee, all the believers who could be called together were assembled. Of this meeting Christ Himself, before His death, had designated the time and place. The angel at the tomb reminded the disciples of His promise to meet them in Galilee. The promise was repeated to the believers who were gathered at Jerusalem during the Passover week, and through them it reached many lonely ones who were mourning the death of their Lord. With intense interest all looked forward to the interview. They made their way to the place of meeting by circuitous routes, coming in from every direction, to avoid exciting the suspicion of the jealous Jews. With wondering hearts they came, talking earnestly together of the news that had reached them concerning Christ. DA 818.2"
"Then the eleven disciples went away into Galilee, into a mountain where Jesus had appointed them."
The EGW passage directly refers to the meeting in Galilee mentioned in Matthew 28:16, elaborating on the circumstances and details surrounding it.
"At the time appointed, about five hundred believers were collected in little knots on the mountainside, eager to learn all that could be learned from those who had seen Christ since His resurrection. From group to group the disciples passed, telling all they had seen and heard of Jesus, and reasoning from the Scriptures as He had done with them. Thomas recounted the story of his unbelief, and told how his doubts had been swept away. Suddenly Jesus stood among them. No one could tell whence or how He came. Many who were present had never before seen Him; but in His hands and feet they beheld the marks of the crucifixion; His countenance was as the face of God, and when they saw Him, they worshiped Him. DA 818.3"
"And when they saw him, they worshipped him: but some doubted."
The EGW passage describes the worship of Jesus by the disciples in Galilee, which is also mentioned in Matthew 28:17. It expands on the scene and adds details not explicitly found in the verse, but the core theme of worship is present in both.
