קבלה אויף קהלת 7:23

Solomon thought to penetrate to the innermost meanings of the Torah, but it baffled him and he exclaimed: “I said, I will get wisdom, but it was far from me” (Eccl. 7, 23). David said: “Open thou mine eyes, that I may behold wondrous things out of thy law” (Ps. 119, 18). We read of Solomon that he “spoke three thousand proverbs; and his songs were a thousand and five” (I Kings 5, 12), and tradition explains this to mean that each of his proverbs admitted of a thousand and five interpretations. Now if this could be said of the words of mere flesh and blood like Solomon, must we not perforce believe that each of the words of the Torah spoken by the Holy One, blessed be He, contains proverbs, songs, and hymns innumerable, sublime mysteries, and truths of Divine Wisdom? Hence: “Who can express the mighty acts of the Lord?”

When you enter those chambers in this world, you will merit to know their hidden depths in the life of the coming world. For, there are many chambers within chambers, and hidden matters within hidden matters, contained within every letter of Torah. Our sages, of blessed memory, therefore stated,³⁹³Midrash Bamidbar Rabba 19:6 “The Holy One, blessed is He, is destined to reveal the secrets of the Torah to the Jewish people.” Even though King Solomon became wiser than any person, he was unable to reach the depths of one of these hidden matters, and said,³⁹⁴Ecclesiastes 7:23 “All this I tested with wisdom; I thought I could become wise, but it is beyond me.” Our sages, of blessed memory, said that this refers to the secret of the Red Heifer (Parah Adumah-פרה אדומה). Know however, that the secret of the Red Heifer (Parah Adumah-פרה אדומה) is only the gateway through which to enter all the other hidden matters. Thus, what King Solomon was saying is that he could not even enter the gateway, let alone the remainder of the inner chambers concealed within. All this is hinted in the verse,³⁹⁵Numbers 19:2 “This is the decree-Chukat-חקת of the Torah,” as explained.
