The Lord bestowed upon these men whom the world admires, priceless intellectual gifts; he endowed them with master minds; but they did not use them to the glory of God. They separated themselves from him as did Satan; but while they separated themselves from him, they still retained many of the precious gems of thought which he had given them, and these they placed in a framework of error to give luster to their own human sentiments, to make attractive the utterances inspired by the prince of evil. It is true that in the writings of pagans and infidels there are found thoughts of an elevated character, which are attractive to the mind. But there is a reason for this.

Ellen White directly references Ezekiel 28:12 in this passage.
"Thou hast been in Eden the garden of God; every precious stone was thy covering, the sardius, topaz, and the diamond, the beryl, the onyx, and the jasper, the sapphire, the emerald, and the carbuncle, and gold: the workmanship of thy tabrets and of thy pipes was prepared in thee in the day that thou wast created. Thou art the anointed cherub that covereth; and I have set thee so: thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire. Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee."
Ellen White directly references Ezekiel 28:13-15 in this passage.
