"Remember that just as soon as you allow your influence to lead away from the straight and narrow path that the Lord has cast up for His people, your prosperity will cease; for God will not be your guide. Again and again the record of Nebuchadnezzar's life has been presented to me to present to you, that you may be warned not to trust in your own wisdom or to make flesh your arm. Do not lower the banner of truth or allow it to drop from your hands in order to unite with the solemn message for these last days anything that will tend to hide the peculiar features of our faith. 8T 162.2"
"Turn not to the right hand nor to the left: remove thy foot from evil."
Both passages warn against straying from the correct path and relying on one's own understanding. The EGW passage explicitly mentions Nebuchadnezzar as an example of someone who failed in this regard, while Proverbs 4:27 offers a general principle of avoiding evil.
