"The revenue of the king and of many of his subjects was greatly increased, but at what a cost! Through the cupidity and shortsightedness of those to whom had been entrusted the oracles of God, the countless multitudes who thronged the highways of travel were allowed to remain in ignorance of Jehovah. PK 72.1"
"My people are destroyed for lack of knowledge: because thou hast rejected knowledge, I will also reject thee, that thou shalt be no priest to me: seeing thou hast forgotten the law of thy God, I will also forget thy children."
Both passages connect a lack of knowledge (of God/Jehovah) with negative consequences. The EGW passage describes the people being left in ignorance, and Hosea describes the people being destroyed for lack of knowledge.
