"New accessions were made continually to the procession, and, with few exceptions, all who joined it caught the inspiration of the hour, and helped to swell the hosannas that echoed and re-echoed from hill to hill and from valley to valley. The shouts went up continually, “Hosanna to the Son of David: Blessed is He that cometh in the name of the Lord! Hosanna in the highest.” DA 572.1"
"And the multitudes that went before, and that followed, cried, saying, Hosanna to the Son of David: Blessed is he that cometh in the name of the Lord; Hosanna in the highest."
EGW directly quotes and describes the scene from Matthew 21:9, making it a clear explicit allusion.
Never before had the world seen such a triumphal procession. It was not like that of the earth's famous conquerors. No train of mourning captives, as trophies of kingly valor, made a feature of that scene. But about the Saviour were the glorious trophies of His labors of love for sinful man. There were the captives whom He had rescued from Satan's power, praising God for their deliverance. The blind whom He had restored to sight were leading the way. The dumb whose tongues He had loosed shouted the loudest hosannas. The cripples whom He had healed bounded with joy, and were the most active in breaking the palm branches and waving them before the Saviour. Widows and orphans were exalting the name of Jesus for His works of mercy to them. The lepers whom He had cleansed spread their untainted garments in His path, and hailed Him as the King of glory.

"The blind receive their sight, and the lame walk, the lepers are cleansed, and the deaf hear, the dead are raised up, and the poor have the gospel preached to them."

"were unlawful, and would not be permitted by the authorities. But they were silenced by the reply of Jesus, “I tell you that, if these should hold their peace, the stones would immediately cry out.” That scene of triumph was of God's own appointing. It had been foretold by the prophet, and man was powerless to turn aside God's purpose. Had men failed to carry out His plan, He would have given a voice to the inanimate stones, and they would have hailed His Son with acclamations of praise. As the silenced Pharisees drew back, the words of Zechariah were taken up by hundreds of voices: “Rejoice greatly, O daughter of Zion; shout, O daughter of Jerusalem: behold, thy King cometh unto thee: He is just, and having salvation; lowly, and riding upon an ass, and upon a colt the foal of an ass.” DA 572.3"
"And he answered and said unto them, I tell you that, if these should hold their peace, the stones would immediately cry out."
The EGW passage directly quotes and explains Luke 19:40 in the context of Jesus's triumphal entry into Jerusalem.
