시편 1:1 할라카: Arukh HaShulchan, Chafetz Chaim, Mishneh Torah, Human Dispositions & Kitzur Shulchan Arukh

And we have been commanded to walk along G-d's path of goodness and righteousness, as the verse says, "you should travel in His ways" (Deut. 26:13). Furthermore it says, "After Hashem your G-d you shall go" (Deut. 13:5). And furthermore it says, "'to travel in all of His ways' (Deut 10:12)- just as He is gracious, you shall also be gracious. Just as he is merciful, you shall also be merciful" (a similar idea appears on Sotah 14b)". And [we are commanded] to emulate His positive actions and positive righteous traits to the best of our ability. It is a positive commandment to be attached to wise men and their students in order to learn from their actions as the verse says, "and to him you shall be devoted" (Deut. 13:5). Is it possible for one to be attached to the Sechinah (divine presence) if it is a consuming fire (Deut. 4:24)? Rather, to be attached to the wise men and their students (Ketuvos 111b), to spread dirt before their feet and to drink their knowledge with thirst, as the verse says, "he who goes with the wise will become wise" (Proverbs 13:20). And furthermore it says, " the praises of a man are that he did not follow the counsel of the wicked" (Psalms 1:1).

And in truth, these people are also in the category of machtiei harabim ["causing the many to sin"]. For because of this evil nature of theirs, whereby they hasten to mock people and to pour out shame and disgrace upon them they compel men who are pure and just in their hearts to follow in their paths — in the beginning, by force, so that those scoffers and "men of the tongue" not publicize them as fools and simpletons or brand them as "hypocrites," and then, as a matter of course, they are dragged after them, for "habit becomes nature." And, as per the well known dictum in the Gemara (Avodah Zarah 18b on Psalms 1:1): "If he goes [with the scoffers], he is destined to stand [with them], and if he stands [with them], he is destined to sit [with them]."...

It is a natural tendency of man to be influenced in his ideas and conduct by his fellows and associates, and to follow the usage of the people of his state. Because thereof, it is necessary for man to be in the company of the righteous, and to sit near the wise, in order to learn from their conduct, and to distance himself from the evil-doers who follow the path of darkness, in order not to learn from their conduct; for of such Solomon said: "He that walketh with wise men shall be wise; but the companion of fools shall smart for it" (Prov. 13.20); and it is also said: "Happy is the man that hath not walked in the counsel of the wicked etc. (Ps. 1.1.). Likewise, if a man be in a state where evil customs prevail and where the people are not following the righteous ways, he should go to a place where the inhabitants are righteous and follow the way of the good. If all the states known to him, or of which intelligence reached him, be followers of a path which is not good, even as it is in our own times, or if he be unable to migrate to a state whose rules of conduct are good, either on account of military operations or on account of sickness, he should isolate himself and live in seclusion, even as it is said on the subject: "Let him sit alone and keep silence" (Lam. 3.28). And, if the inhabitants of his state be evildoers and sinners, who deny him the right of residence in the state unless he become assimilated with them, and follows their evil conduct, he should go forth and dwell in caves, or cliffs, or deserts, but not accustom himself in the way of the sinners, even as it is said on the subject: "Oh that I were in the wilderness,¹See Berakot, 35b. G. in a lodging place of wayfaring men" (Jer. 9.1.).
