Isaiah 50:10

Who is among you that feareth the Lord— After the Messiah had prophetically described his condition among the Jews, he addresses himself to the Jewish people, who, being divided into two classes, one of believers, his disciples, the other of the rebellious, who, he foresaw, would perish in their own devices; he applies to both, but in a different manner; comforting the former in the doubtful beginnings of the new oeconomy; and foretelling to the latter the destruction which would come upon them. The consolatory address in this verse is of perpetual use: for, who may not apply it in the doubtful and uncertain state of his affairs to the support of his faith and hope? It is however, in its literal sense here, to be restrained to that solicitude and anxiety, that heaviness and sorrow, which involved the first believers, from the unsettled and persecuted state of the church. See Hebrews 10:35.
