"Ahithophel had been held in high esteem for his wisdom, but he was destitute of the enlightenment which comes from God. “The fear of the Lord is the beginning of wisdom” ( Proverbs 9:10 ); and this, Ahithophel did not possess, or he could hardly have based the success of treason upon the crime of incest. Men of corrupt hearts plot wickedness, as if there were no overruling Providence to cross their designs; but “He that sitteth in the heavens shall laugh: the Lord shall have them in derision.” Psalm 2:4 . The Lord declares: “They would none of My counsel: they despised all My reproof. Therefore shall they eat of the fruit of their own way, and be filled with their own devices. For the turning away of the simple shall slay them, and the prosperity of fools shall destroy them.” Proverbs 1:30-32 . PP 739.1"
"The fear of the Lord is the beginning of wisdom: and the knowledge of the holy is understanding."
The EGW passage directly quotes Proverbs 9:10 and uses it as a basis for discussing Ahithophel's lack of true wisdom.
"He that sitteth in the heavens shall laugh: the Lord shall have them in derision."
EGW directly quotes Psalm 2:4.
"They would none of my counsel: they despised all my reproof."
EGW directly quotes Proverbs 1:30.
"They would none of my counsel: they despised all my reproof. Therefore shall they eat of the fruit of their own way, and be filled with their own devices. For the turning away of the simple shall slay them, and the prosperity of fools shall destroy them."
Ellen White directly references Proverbs 1:30-32 in this passage.
"have been slain, unless the Lord had directly interposed to save him. But a wisdom higher than that of the renowned Ahithophel was directing events. “The Lord had appointed to defeat the good counsel of Ahithophel, to the intent that the Lord might bring evil upon Absalom.” PP 739.2"
"And Absalom and all the men of Israel said, The counsel of Hushai the Archite is better than the counsel of Ahithophel. For the Lord had appointed to defeat the good counsel of Ahithophel, to the intent that the Lord might bring evil upon Absalom."
This is a direct quote from 2 Samuel 17:14, making it an explicit allusion. EGW uses the verse to emphasize God's intervention in human affairs.
