"The disciples feared for their own lives, and they all forsook Him and fled. Jesus was left alone in the hands of the murderous mob. Oh, what a triumph of Satan then! And what sadness and sorrow with the angels of God! Many companies of holy angels, each with a tall commanding angel at their head, were sent to witness the scene. They were to record every insult and cruelty imposed upon the Son of God, and to register every pang of anguish which Jesus should suffer; for the very men who joined in this dreadful scene are to see it all again in living characters. EW 168.1"
"But all this was done, that the scriptures of the prophets might be fulfilled. Then all the disciples forsook him, and fled."
The EGW passage directly references the disciples forsaking Jesus and fleeing, which is described in Matthew 26:56. While the EGW passage adds details about the angels and Satan's triumph, the core event of the disciples' abandonment is directly linked to the biblical verse.
