"sealed its rejection of Christ by the persecution of His disciples, and the apostles turned to the Gentiles, A.D. 34. The first 490 years of the 2300 having then ended, 1810 years would remain. From A.D. 34, 1810 years extend to 1844. “Then,” said the angel, “shall the sanctuary be cleansed.” All the preceding specifications of the prophecy had been unquestionably fulfilled at the time appointed. GC 410.1"
"Then Paul and Barnabas waxed bold, and said, It was necessary that the word of God should first have been spoken to you: but seeing ye put it from you, and judge yourselves unworthy of everlasting life, lo, we turn to the Gentiles."
Both passages discuss the turning away from the Jewish people and the subsequent focus on the Gentiles. The EGW passage uses this event as a starting point for calculating the remaining years of the 2300-day prophecy, directly referencing the historical shift described in Acts.
"With this reckoning, all was clear and harmonious, except that it was not seen that any event answering to the cleansing of the sanctuary had taken place in 1844.

"And he said unto me, Unto two thousand and three hundred days; then shall the sanctuary be cleansed."

He would not leave His word involved in doubt and uncertainty. Though many abandoned their former reckoning of the prophetic periods and denied the correctness of the movement based thereon, others were unwilling to renounce points of faith and experience that were sustained by the Scriptures and by the witness of the Spirit of God. They believed that they had adopted sound principles of interpretation in their study of the prophecies, and that it was their duty to hold fast the truths already gained, and to continue the same course of Biblical research. With earnest prayer they reviewed their position and studied the Scriptures to discover their mistake. As they could see no error in their reckoning of the prophetic periods, they were led to examine more closely the su…
"Thou leddest thy people like a flock by the hand of Moses and Aaron."
The EGW passage describes God leading His people through the advent movement. Psalm 77:20 speaks of God leading His people like a flock. While not a direct quote or allusion, the thematic parallel of God's guidance is present.
