이사야 5:7 할라카: Mishneh Torah, Torah Study

A student who did not attain judicial rank but renders decisions behold him, he is a wicked, arrogant fool, of whom it is said: "For she hath cast down many wounded" (Prov. 7.26). Likewise a sage who attained judicial rank but does not render decisions, behold him, he is withholding the Torah, and distributes obstacles in the path of the blind, concerning whom it is said: "Yea, many strong men have been slain by her" (Ibid.). Those petty students who have not increased their knowledge of the Torah as they should and yet are seeking to appear great before the ignorant, and among their towns-people, jumping forward to occupy a front seat to judge and instruct among Israel, are the ones who multiply strife, and the ones who destroy the world, who extinguish the light of the Torah, and despoil the vineyard of the Lord of Hosts, concerning whom Solomon in his wisdom said: "Take us the foxes, the little foxes, that spoil the vineyards". (Song of Songs, 2.15.).⁴Abodah Zarah, 22b; Sotah, 19a.
