כִּ֣י ׀ אֱוִ֣יל עַמִּ֗י אוֹתִי֙ לֹ֣א יָדָ֔עוּ בָּנִ֤ים סְכָלִים֙ הֵ֔מָּה וְלֹ֥א נְבוֹנִ֖ים הֵ֑מָּה חֲכָמִ֥ים הֵ֙מָּה֙ לְהָרַ֔ע וּלְהֵיטִ֖יב לֹ֥א יָדָֽעוּ׃
Sebab bangsa-Ku bodoh, Aku tidak mereka kenal; mereka anak-anak yang dungu dan tidak berpengertian; mereka pandai berbuat jahat, tetapi berbuat baik tidak mereka ketahui.
Rashi
they have become foolish Heb. נואלו, an expression of אויל, a fool, as the Targum renders: אטפשו.
Rambam
And when you know the intellectual virtues and the dispositional virtues; and you know every type of them - if you want, study of wisdom and practice - and you know the mean and the ways of deeds that can be called good; and [know] the slight supplement to the mean which is from the famous actions of the pious ones; and [when you] know the supplement and the lack which are both bad -- just that one of them is more fit to [be called] evil and the other is called a transgression or an incorrect action, and the example with this is that caution is completely good without a doubt and much desire is completely bad without a doubt and the lack of feeling for enjoyment is actually not like much desire even though it is [also] bad and [so] it is called a transgression or an incorrect action, [such that] leaving caution slightly towards the side of lack of feeling is fit for the complete ones - and when you understand this matter, you will know that one who leaves caution slightly is called pious as we prefaced and that the lack of feeling is called a transgression, and that is why it stated about the nazirite (Numbers 6:11), "from that which he transgressed upon the soul," as we explained in the fourth chapter (Eight Chapters 4); and [when you understand] all of what we have prefaced and elucidated, you will know which [person] from among people is fitting to be called a boor and who is fitting to be called an ignoramus and who is fitting to be called and unformed person and who is fitting to be called a wise man and who is fitting to be called evil and who is fitting to be called a sinner. These seven names apply to seven people according to their having from the virtues and the vices and their study of the intellectual [virtues], as per what has come earlier in our commentary. And they already [added] names according to the properties of a man, as with the man who has vices in his traits - and he is called evil, as we have explained - but if he [also] has intellectual virtues that he uses for evil things, such a one is called by the sages a clever evildoer. And if he is an evildoer who hurts people - meaning to say that among his character vices are matters that hurt people, like brazenness and cruelty and [traits] similar to them - such a one is called a bad evildoer. And so [too] the one who has intellectual virtues and dispositional vices is called a wise man to do evil, as it states in the verse about someone like this (Jeremiah 4:22), "they are wise men to do evil; but to do good, they do not know" - meaning to say that they use their intellectual virtues for bad actions and not for good actions. But the man who has all of the virtues gathered in him - the intellectual [ones] and the dispositional virtues - to the point that there is no intellectual virtue and no dispositional virtue not in him, and this is rarely found and the philosophers would say that finding such a person is very unlikely but not impossible and when they find him, they would call him a Godly man. And so [too], the sages called him in our language a man of God. And I say that this man is called an angel of the Lord, as it stated (Judges 2:1), "And the angel of the Lord went up from Gilgal." And the philosophers have said that it is impossible to find a man that has all of the vices gathered in him to their very end without intellectual [virtues] or ones of disposition to the point that he does not have virtue at all. And if one is found and this is improbable, they give him the name, 'an animal from the bad, dangerous animals.' And so [too] did Shlomo call him, a 'bereaved bear,' which is the gathering of stupidity and damage. And [of] these five compound names, four of them are to disparage - and they are the clever evildoer, the bad evildoer, the wise man to do evil and the bereaved bear - and one is for greatness, and there is nothing greater than it - and that is the man of God or the angel of the Lord. And Scripture has already elucidated that a man that has all of the intellectual and dispositional virtues found in him is called an angel of the Lord, and that is its stating (Malachi 2:7), "For the lips of a priest guard knowledge, and they seek Torah from his mouth; for he is an angel of the Lord of Hosts." And knowledge includes all of the intellectual virtues, as he will not be complete without them. And its stating, "they seek Torah from his mouth," is a proof of his completeness in dispositional virtues - as we have explained in the fourth chapter (Eight Chapters 4), that it is the intention of the Torah. And for [this reason], it states (Proverbs 3:17), "and all of its ways are peace." And we have already elucidated there (Eight Chapters 4) that peace is also from the dispositional virtues. And after [these indications of his completeness in the verse in Malachi], it stated, "for he is angel of the Lord of Hosts."
Tur HaArokh
אנשי חיל, “competent people,” people capable of dealing with the masses, i.e. people who have been endowed with numerous qualities, otherwise they would not be equal to the task. Having summed up the nature of such people, Yitro proceeds to list the specific qualities such people must possess in order to carry out their duties satisfactorily. Before referring to such people’s common sense, he mentions that their motivations must be above board, such as their being G’d-fearing, not greedy for money, truthful, etc., but all this is not enough unless they have been endowed with common sense, such as being נבונים. The latter quality need not be spelled out, as it is self-evident. [both Isaiah 5,21, and Jeremiah 4,22, refer to the basic requirement of this “common sense.” It is also the first attribute mentioned by Joseph in his advice to Pharaoh to appoint people who would administer the surplus during the seven bountiful years to come. Genesis Ed.] When reviewing these events in Deuteronomy 1,12, Moses does mention that he had asked the people to furnish him men endowed with common sense in addition to the other attributes as his assistants. [certain details which Moses saw fit to spell out to the common people, Yitro did not have to spell out to his brilliant son-in-law. Ed.] It is also possible that when we read in verse 25 that Moses selected men מכל ישראל, this term already includes that he had narrowed down the selection to the elite of the people, so that he did not need to repeat more than the term אנשי חיל to show that he had taken Yitro’s advice to heart.
