"“I was shown some things in regard to you. I saw that you were deceived in regard to yourself. You have given occasion for the enemies of our faith to blaspheme, and to reproach Sabbathkeepers. By your indiscreet course, you have closed the ears of some who would have listened to the truth. I saw that we should be as wise as serpents and as harmless as doves. You have manifested neither the wisdom of the serpent nor the harmlessness of the dove. 1T 359.1"
"Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves."
EGW directly quotes and applies the phrase 'wise as serpents and harmless as doves' from Matthew 10:16, making this a clear and intentional allusion.
"For the name of God is blasphemed among the Gentiles through you, as it is written."
The EGW passage states that the person's actions have 'given occasion for the enemies of our faith to blaspheme,' which directly echoes the sentiment in Romans 2:24, 'For the name of God is blasphemed among the Gentiles through you.'

“Satan has been stirring you up. He would not let you rest until you should express your sentiments upon the side of the powers of darkness, thus strengthening the hands of the wicked, whom God has cursed. You have cast your influence on the wrong side, with those whose course of life is to sow thorns and plant misery for others. I saw you casting your influence with a degraded company, a Godforsaken company; and angels of God fled from you in disgust. I saw that you were utterly deceived. Had you followed the light which God has given you, had you heeded the instructions of your brethren, had you listened to their advice, you would have saved yourself and saved the precious cause of truth from reproach. But notwithstanding all the light given, you have given publicity to your sentiments. Unless you undo what you have done, it will be the duty of God's people to publicly withdraw their sympathy and fellowship from you, in order to save the impression which must go out in regard to us a…
"For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."
The EGW passage speaks of being on the side of the 'powers of darkness' which aligns with the Ephesians verse about wrestling against 'the rulers of the darkness of this world'.
"Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of sinners, nor sitteth in the seat of the scornful."
Both passages deal with avoiding the company and counsel of the ungodly. The EGW passage speaks of a 'degraded company' and casting influence on the wrong side, which echoes the sentiment of Psalm 1:1.
