"For the next trial a lowlier instrument was chosen—a young man, so humble in appearance that he was coldly treated even by the professed friends of reform. But what could such a one do where Farel had been rejected? How could one of little courage and experience withstand the tempest before which the strongest and bravest had been forced to flee? “Not by might, nor by power, but by My Spirit, saith the Lord.” Zechariah 4:6 . “God hath chosen the weak things of the world to confound the things which are mighty.” “Because the foolishness of God is wiser than men; and the weakness of God is stronger than men.” 1 Corinthians 1:27, 25 . GC 232.2"
"Then he answered and spake unto me, saying, This is the word of the Lord unto Zerubbabel, saying, Not by might, nor by power, but by my spirit, saith the Lord of hosts."
Ellen White directly references Zechariah 4:6 in this passage.
