חָכָ֣ם יָ֭רֵא וְסָ֣ר מֵרָ֑ע וּ֝כְסִ֗יל מִתְעַבֵּ֥ר וּבוֹטֵֽחַ׃
O sábio teme e desvia-se do mal, mas o tolo é arrogante e dá-se por seguro.
Rabbeinu Yonah
And do not be wicked in your own eyes: That he not be an evildoer in his own eyes, [such] that he not be able to repent. As it comes out that this one gives up on repentance - and if a sin comes to his hand, it is (as if) it is permitted to him, since it comes to his mind that it is light compared to the heavy ones that he has transgressed. And he should also not be righteous in his own eyes, as they said in Tractate Niddah 30b, "The embryo is made to swear in the womb of his mother: Even if the entire world says that you are righteous, be like an evildoer in your own eyes" - and not an actual evildoer, but rather he should be half guilty and half meritorious in his own eyes. [If he] did one [more] commandment, happy is he - as he has determined that he be on the side of merit; ]if he] did one more sin, woe to him - as he has determined himself to be on the side of guilt. And this is that which they said in Vayikra Rabbah (Kiddushin 40a), "A man should always see himself as if he is half meritorious and half guilty, as it is stated (Proverbs 14:16), 'A wise man is afraid and evades evil.'" He wanted to say that even though he has evaded evil, the wise man is afraid because he is evil in his own eyes. And it comes out that he runs after the commandments, so that they determine him to be on the side of merit. And he runs from the sins, so that they not determine him to be on the side of guilt.
