Halakhah su Genesi 1:31

(Vav) And see that which our teacher Rabbi Moshe Almosnino (Greece, 16th century) [writes] in his commentary on the Book of Ecclesiastes (on Ecclesiastes 10:1), “Dead flies turn the perfumer’s ointment fetid and putrid; so a little folly outweighs massive wisdom.” As he writes that those that have straight minds are not so incisive; as incisiveness comes as a result of confusion. [And] since those whose minds are not straight have limitations on their [thinking], when [they are therefore required to] push their minds, it brings great incisiveness. [This is] as we see with the burning of a fire – when a little water is poured upon it, the fire grows and has bigger flames; with ‘greater height and greater power’ [coming] from the bonfire than before, without the water. So is this thing: If the mind has a little bit opposing it – which is “the little folly” – then the mind will push against it and the mind will become more incisive. See there. And with this it appears that [we can] explain the statement of the Sages, may their memory be blessed, “‘And behold, it was very good’ (Gen. 1:31) – ‘good,’ that is the good impulse; ‘very good,’ that is the evil impulse” (Bereishit Rabbah 9:7). And that is because the evil impulse is called a fool and the good impulse is called a wise man.²⁷Kohelet Rabbah 4:13. Therefore when there is opposition from the side of folly, which is the evil impulse, against the approach of wisdom, which is the good impulse; the mind, which is the good impulse, pushes against the folly and rises to much [higher] levels than it was before. [And this] would not be the case if there was no evil impulse opposing it – there would [then] not have been this overcoming. And [so] it would have only been good from the angle of itself, but not “very [good].” However through the opposing evil impulse, the good impulse pushes and becomes “very good.” And this appears to be the intention of the statement of the Sages, may their memory be blessed, “‘Happy is the man who fears the Lord’ (Ps. 112:1) – happy is the man, but not the woman? Rav Amram said that Rav said, ‘Happy is he if he repents when he is [still a] man’” (Avodah Zarah 19a). [This is] meaning, that [when he is still young enough], he has opposition from the side of the evil impulse and overcomes it. For then he will very much desire His commandments. (Hence, this is “very good.”) But if he is old and his desires have withered and his impulse has become weak – even though he desires the commandments, it will not be [in a state of “very”], as mentioned above.

Rav Dov Brisman (a prominent Rav and Dayan in Philadelphia) presents quite a compelling defense of this practice in Teshuvot Shalmei Chovah (Y.D. 63). Rav Brisman notes other areas in which we seem not to treat pesukim as Chazal would prefer. The issue he focuses on is the common practice to recite fragments of pesukim, such as “Vayehi erev vayehi voker yom hashishi” (Bereishit 1:31) at the start of Friday night kiddush and “Al kein beirach Hashem et yom hashabbat vayekashsheihu” (Shemot 20:10) at the start of Shabbat morning kiddush, despite the Gemara's apparent injunction against splitting a pasuk which Moshe Rabbeinu did not split in the Torah (Taanit 27b). While many, such as Mishnah Berurah (289:2) and Rav Yosef Dov Soloveitchik (Nefesh HaRav p.159), adopt a strict practice not to recite fragments of pesukim, common practice is to be lenient, as noted by the Mishnah Berurah.

It is from the roots of the commandment that God, blessed be He, created His world with wisdom, with understanding and with knowledge, and [so] He made and formed all of the forms according to that which it was fitting for its matter to be, to be designed [according to] the design of the world - and blessed is He that knows [this]. And this is what is stated about the story of creation (Genesis 1:31), "And God saw everything that He had done, and behold, it was very good." And His seeing, blessed be He, is His knowledge and contemplation about things; as He, blessed be He, does not need seeing things with the eye after the act, due to His great level; since everything is revealed and known and apparent in front of Him before the act, [just] like after the act. But the Torah speaks to people with words directed to them, and it calls things by the name of things that are aimed at them, as it only possible to speak with a creature with what is known to him - as who can understand what he does not have the power to understand? And about what is similar to this, they, may their memory be blessed, said (Mekhilta d'Rabbi Yishmael 19:18:2), [it is] in order to break [to assuage] the ear to that which it can hear. And in that God knew that everything He made was designed perfectly for its matter that it needed in His world, He commanded to each and every specie to make its 'fruit' for its specie - as it is written in the Order of Bereshit - and that the species not mix, lest it will take away from their perfection and He [therefore] not command His blessing upon them. And according to what it seems in our thoughts, it is from this root that we were prevented from mating beasts [in a] forbidden mixture. And likewise from this reason were we warned about this, combined with another reason that we already wrote about species of seeds and trees (Sefer HaChinukh 62).
