이사야 51:1의 Musar

He should be zealous to seek knowledge of the Torah and knowledge of the Creator, as it is written. "And let us know, eagerly strive to know the Lord" (Hos. 6:3). Thus said the Sages: "Betake thyself to a place of Torah" (Aboth 4:14). And a man should be alert to seek justice, as it is written : "Justice, justice shall you pursue" (Deut. 16:20). And it is written, "Hearken to Me, ye that follow after righteousness, Ye that seek the Lord" (Is. 51:1). It is necessary to be quick in copying out the books which one needs for one's study. When he sees or hears a new thing, he should be alert to write it down and not delay until it is forgotten from his heart.
