Comentario citado sobre Eclesiastés 7:16

A more rational approach: The author speaks of the Kingdom of Heaven. Solomon warns man not to approach it over and beyond one’s mental capacities. We find other verses in Scripture describing G’d as מושל, ruler, such as Psalms 22,29: כי לה' המלוכה ומושל בגויים, “for kingship is the Lord’s and He rules the nations.” Keeping this thought in mind, Solomon warns you that when you sit down to eat with the ruler you better be clear what nearness to G’d entails, i.e. who qualifies for such an elevated station in life. You must appreciate that the food served at G’d’s table is soul-food, not of the type that is served at the table of a king of flesh and blood. The food you receive there is known as חכמה, the spiritual equivalent to the לחם, “bread,” served here on earth by human kings. The words בין תבין את אשר לפניך mean in essence that you must be sure to comprehend things about the nature of G’d by what is לפניך, “by what is before your eyes,” i.e. by the historical record of G’d’s actions. This is also what David said in Psalms 8,4: “when I behold Your heavens, the work of Your fingers, the moon and the stars that You set in place.” The word בין, “between,” suggests that there are two distinct kinds of insights that one must possess in order to properly appreciate the grandeur of G’d and His impact on history as well as on our individual fates. The very concept G’d, Creator, is not a point of departure in one’s thinking but is a conclusion one arrives at after having weighed all the phenomena we are familiar with. This is the meaning of Deut. 4,39: והשבות אל לבביך כי ה' הוא האלו-הים, “and let your heart come to the conclusion that the Lord is your G’d, etc.” When Elijah experienced a personal revelation at Mount Chorev after he had been disillusioned subsequent to what he thought would be G’d’s triumph at Mount Carmel, he had to experience a variety of supernatural phenomena before finally, a most insignificant phenomenon, a whisper, proved to be the real thing, the Presence of G’d (Kings I 19,11-12).
It is due to such considerations that Solomon hints that several insights have to be gained in order to appreciate certain truths about G’d.
If one is an intellectually oriented person, Solomon warns that one should not allow one’s intellectual curiosity to cause one to bite off more than one can chew (intellectually speaking); he couches the warning in these words: “thrust a knife in your gullet.” What he means is simple: you would do better to commit suicide than to reach beyond your intellectual capacity in coming close to the Lord. Solomon phrases this more clearly in Kohelet 7,16: “don’t act the wise man to excess or you will be dumbfounded.” You can see what happened to the two sons of Aaron who were guilty precisely of the arrogance of overestimating their mental/moral capabilities when they were described at the revelation on Mount Sinai as feasting their eyes on divine visions, breaching barriers that had been designed to prevent precisely such a disaster from occurring (compare Exodus 19,24 as well as 24,10). Death was decreed for them because they approached domains which were beyond what they were allowed to approach. This is the meaning of the opening lines of our Parshah.

[According to the sources cited above,] it seems reasonable to assume that regardless of a person’s toil and labor, he will lack the capacity to merit more [Torah knowledge] than the potential he received [from God], just as it is difficult for one to achieve wealth if it is not his mazal, his destiny. I would also explain that this is what Koheles states in Eccl. 7:16: “Do not be overly righteous or excessively wise: why become demented?” [The verse must be conveying that there is no benefit in attempting to be more wise or righteous than his innate abilities]. Otherwise, the meaning of “overly” and “excessive” is ambiguous.

One cannot focus exclusively only one Torah value. This is the import of the teaching of Shlomo HaMelech in Kohelet (7:16) that one should refrain from being too wise or too pious. Piety and wisdom constitute core Torah values. However, if one focuses exclusively on only one of these values, to the exclusion of all others, one has distorted the teachings and meaning of the Torah.
