27:17 While laboring at Thessalonica, Paul had so fully covered the subject of the signs of the times, showing what events would occur prior to the revelation of the Son of man in the clouds of heaven, that he did not think it necessary to write at length regarding this subject. He, however, pointedly referred to his former teachings. "Of the times and the seasons," he said, "ye have no need that I write unto you. For yourselves know perfectly that the day of the Lord so cometh as a thief in the night. For when they shall say, Peace and safety; then sudden destruction cometh upon them."
