"“And if any man will hurt them, fire proceedeth out of their mouth, and devoureth their enemies: and if any man will hurt them, he must in this manner be killed.” Revelation 11:5 . Men cannot with impunity trample upon the word of God. The meaning of this fearful denunciation is set forth in the closing chapter of the Revelation: “I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book: and if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.” Revelation 22:18, 19 . GC 268.1"
"And if any man will hurt them, fire proceedeth out of their mouth, and devoureth their enemies: and if any man will hurt them, he must in this manner be killed."
Ellen White directly references Revelation 11:5 in this passage.
"Such are the warnings which God has given to guard men against changing in any manner that which He has revealed or commanded. These solemn denunciations apply to all who by their influence lead men to regard lightly the law of God. They should cause those to fear and tremble who flippantly declare it a matter of little consequence whether we obey God's law or not. All who exalt their own opinions above divine revelation, all who would change the plain meaning of Scripture to suit their own convenience, or for the sake of conforming to the world, are taking upon themselves a fearful responsibility. The written word, the law of God, will measure the character of every man and condemn all whom this unerring test shall declare wanting. GC 268.2"
"Ye shall not add unto the word which I command you, neither shall ye diminish ought from it, that ye may keep the commandments of the Lord your God which I command you."
EGW's statement about not changing what God has revealed directly reflects the principle in Deuteronomy 4:2 against adding to or diminishing from God's word.
"Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven."
Both passages address the importance of upholding and teaching God's commandments. Matthew 5:19 emphasizes the consequences of breaking even the least commandment and teaching others to do so. The EGW passage echoes this sentiment by warning against leading others to disregard God's law.
"But in vain they do worship me, teaching for doctrines the commandments of men."
Both passages address the issue of replacing God's commands with human doctrines. EGW speaks of exalting opinions above divine revelation, while Matthew 15:9 condemns teaching the commandments of men as doctrines.
"But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed."
Both passages warn against altering or contradicting the established divine message. Galatians 1:8 condemns preaching a different gospel, while EGW warns against changing God's revealed law or exalting personal opinions above divine revelation.
"“When they shall have finished [are finishing] their testimony.” The period when the two witnesses were to prophesy clothed in sackcloth, ended in 1798. As they were approaching the termination of their work in obscurity, war was to be made upon them by the power represented as “the beast that ascendeth out of the bottomless pit.” In many of the nations of Europe the powers that ruled in church and state had for centuries been controlled by Satan through the medium of the papacy. But here is brought to view a new manifestation of satanic power. GC 268.3"
"And when they shall have finished their testimony, the beast that ascendeth out of the bottomless pit shall make war against them, and shall overcome them, and kill them."
EGW directly quotes and interprets Revelation 11:7, connecting it to the events surrounding 1798 and the rise of a new manifestation of satanic power. The connection is direct and significant.
