"Instead of the leading men in this war trusting in the God of Israel, and directing their armies to trust in the only One who can deliver them from their enemies, the majority inquire of the prince of devils and trust in him. Deuteronomy 32:16-22 . Said the angel: “How can God prosper such a people? If they would look to and trust in Him; if they would only come where He could help them, according to His own glory, He would readily do it.” 1T 364.3"
"They provoked him to jealousy with strange gods, with abominations provoked they him to anger. They sacrificed unto devils, not to God; to gods whom they knew not, to new gods that came newly up, whom your fathers feared not. Of the Rock that begat thee thou art unmindful, and hast forgotten God that formed thee. And when the Lord saw it, he abhorred them, because of the provoking of his sons, and of his daughters. And he said, I will hide my face from them, I will see what their end shall be: for they are a very froward generation, children in whom is no faith. They have moved me to jealousy with that which is not God; they have provoked me to anger with their vanities: and I will move them to jealousy with those which are not a people; I will provoke them to anger with a foolish nation. For a fire is kindled in mine anger, and shall burn unto the lowest hell, and shall consume the earth with her increase, and set on fire the foundations of the mountains."
Ellen White directly references Deuteronomy 32:16-22 in this passage.
