Rabbi Simeon Bar Yohai in the 2th century wrote:
"If a man looks upon the Torah as merely a book presenting narratives and everyday matters, alas for him! Such a torah, one treating with everyday concerns, and indeed a more excellent one, we too, even we, could compile. More than that, in the possession of the rulers of the world there are books of even greater merit, and these we could emulate if we wished to compile some such torah. But the Torah, in all of its words, holds supernal truths and sublime secrets.
Thus the tales related in the Torah are simply her outer garments, and woe to the man who regards that outer garb as the Torah itself, for such a man will be deprived of portion in the next world. Thus David said:" Open Thou mine eyes, that I may behold wondrous things out of Thy law" (Psalms 119:18), that is to say, the things that are underneath. See now. The most visible part of a man are the clothes that he has on, and they who lack understanding, when they look at the man, are apt not to see more in him than these clothes. In reality, however, it is the body of the man that constitutes the pride of his clothes, and his soul constitutes the pride of his body.
Woe to the sinners who look upon the Torah as simply tales pertaining to things of the world, seeing thus only the outer garment. But the righteous whose gaze penetrates to the very Torah, happy are they. Just as wine must be in a jar to keep, so the Torah must also be contained in an outer garment. That garment is made up of the tales and stories; but we, we are bound to penetrate beyond."
