"Zechariah then saw the powers that had “scattered Judah, Israel, and Jerusalem,” symbolized by four horns. Immediately afterward he saw four carpenters, representing the agencies used by the Lord in restoring His people and the house of His worship. See verses 18-21 . PK 581.1"
"Then lifted I up mine eyes, and saw, and behold four horns."
EGW directly references and interprets Zechariah 1:18.
"And the Lord shewed me four carpenters."
EGW directly references and interprets Zechariah 1:20.
"“I lifted up mine eyes again,” Zechariah said, “and looked, and behold a man with a measuring line in his hand. Then said I, Whither goest thou? And he said unto me, To measure Jerusalem, to see what is the breadth thereof, and what is the length thereof. And, behold, the angel that talked with me went forth, and another angel went out to meet him, and said unto him, Run, speak to this young man, saying, Jerusalem shall be inhabited as towns without walls for the multitude of men and cattle therein: for I, saith the Lord, will be unto her a wall of fire round about, and will be the glory in the midst of her.” Zechariah 2:1-5 . PK 581.2"
"I lifted up mine eyes again, and looked, and behold a man with a measuring line in his hand. Then said I, Whither goest thou? And he said unto me, To measure Jerusalem, to see what is the breadth thereof, and what is the length thereof. And, behold, the angel that talked with me went forth, and another angel went out to meet him, And said unto him, Run, speak to this young man, saying, Jerusalem shall be inhabited as towns without walls for the multitude of men and cattle therein: For I, saith the Lord, will be unto her a wall of fire round about, and will be the glory in the midst of her."
Ellen White directly references Zechariah 2:1-5 in this passage.
"And said unto him, Run, speak to this young man, saying, Jerusalem shall be inhabited as towns without walls for the multitude of men and cattle therein:"
EGW directly quotes and references Zechariah 2:4 to support her description of the vision of Zechariah.
"God had commanded that Jerusalem be rebuilt; the vision of the measuring of the city was an assurance that He would give comfort and strength to His afflicted ones, and fulfill to them the promises of His everlasting covenant. His protecting care, He declared, would be like “a wall of fire round about;” and through them His glory would be revealed to all the sons of men. That which He was accomplishing for His people was to be known in all the earth. “Cry out and shout, thou inhabitant of Zion: for great is the Holy One of Israel in the midst of thee.” Isaiah 12:6 . PK 581.3"
"Cry out and shout, thou inhabitant of Zion: for great is the Holy One of Israel in the midst of thee."
EGW directly quotes Isaiah 12:6.
"For I, saith the Lord, will be unto her a wall of fire round about, and will be the glory in the midst of her."
EGW's statement about God's protecting care being like a 'wall of fire' is a clear echo of Zechariah 2:5. While not a direct quote, the imagery and concept are too similar to ignore.
