"Crushed by despondency, grief, and despair, the disciples met together in the upper chamber, and closed and fastened the doors, fearing that the fate of their beloved Teacher might be theirs. It was here that the Saviour, after His resurrection, appeared to them. AA 26.1"
"Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, came Jesus and stood in the midst, and saith unto them, Peace be unto you."
Both passages describe the disciples meeting in a closed room out of fear, and Jesus appearing to them. The EGW passage amplifies the emotional state of the disciples.
"For forty days Christ remained on the earth, preparing the disciples for the work before them and explaining that which heretofore they had been unable to comprehend. He spoke of the prophecies concerning His advent, His rejection by the Jews, and His death, showing that every specification of these prophecies had been fulfilled. He told them that they were to regard this fulfillment of prophecy as an assurance of the power that would attend them in their future labors. “Then opened He their understanding,” we read, “that they might understand the Scriptures, and said unto them, Thus it is written, and thus it behooved Christ to suffer, and to rise from the dead the third day: and that repentance and remission of sins should be preached in His name among all nations, beginning at Jerusalem.” And He added, “Ye are witnesses of these things.” Luke 24:45-48 . AA 26.2"
"Then opened he their understanding, that they might understand the scriptures, And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day: And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem. And ye are witnesses of these things."
Ellen White directly references Luke 24:45-48 in this passage.
