ציטירנדיקער פּירוש אויף ישעיהו 47:1

It is written in Proverbs 20:4, “The sluggard will not plow when it is winter; therefore shall he beg in harvest, and have nothing.” The wise one [Solomon], who was imbued with the Divine Spirit, did not come to tell us what even small children know. As explained by Rashi’s commentary on that verse, derived from the Midrash Rabbah on the Torah portion Nitzavim, this verse is a parable and analogy, referring to the Torah. For we already know from other [Talmudic sources] that the toil and labor applied to Torah [study] is compared to bread. Tractate Hagigah 14a states, pertaining to the verse, “Come, eat of my bread…,”²²Prov. 9:5, “Come, eat of my bread and drink of the wine that I have mixed.” [that bread] refers to the Talmud.²³See Ha’amek Davar, Deut. 28:2, where the Netziv explains that the word lehem denotes how the Torah creates a strong connection between God and Israel which cannot be severed. It resembles the Hebrew word laham, which means to weld or glue two things together strongly. Scripture compares the toil of Torah in one’s youth to “plowing,” while “harvest” is referring to a person later in life, who possesses a clear mind and benefits others with his wisdom. [King Solomon] is stating that if one does not toil by applying analysis in his youth,²⁴This is the parable of planting in the winter. he will beg for explanations of the Torah and receive nothing.²⁵This means that he will not receive an understanding of clearly-defined laws. We now need to understand that just as plowing when done by the elderly is not successful, because at a weaker time of life one can not hoe well, so there is no point in man harvesting in his youth, i.e., reaping the fruit [of Torah] too early, so that it cannot be restored or improved by means of great analysis. The fruit of the tree of life is fragile and delicate,²⁶Isa.47:1. and its essential taste and aroma come when it has matured and not when it is unripe.
