"I was shown that my husband's course has not been perfect. He has erred sometimes in murmuring and in giving too severe reproof. But from what I have seen, he has not been so greatly at fault in this respect as many have supposed and as I have sometimes feared. Job was not understood by his friends. He flings back upon them their reproaches. He shows them that if they are defending God by avowing their faith in Him and their consciousness of sin, he has a more deep and thorough knowledge of it than they ever had. “Miserable comforters are ye all,” is the answer he makes to their criticisms and censures. “I also,” says Job, “could speak as ye do: if your soul were in my soul's stead, I could heap up words against you, and shake mine head at you.” But he declares that he would not do this. “I,” he says, “would strengthen you with my mouth, and the moving of my lips should assuage your grief.” 3T 508.1"
"I have heard many such things: miserable comforters are ye all."
The EGW passage directly quotes Job 16:2 ('Miserable comforters are ye all') and discusses the context of Job's interactions with his friends, making it a clear and intentional reference.
