Commentaire sur La Genèse 37:12

לרעות את צאן TO FEED THE FLOCK — The word את has dots above it, to denote that they went only to feed themselves (Genesis Rabbah 84:13).

וילכו אחיו לרעות צאן, there are dots above the letters of the word את. The sages in Bereshit Rabbah 84,13 suggest that the Torah meant that the brothers were tending themselves, i.e. they distanced themselves from their father in order to escape supervision and to follow their personal inclinations in matters of food and drink and to do in Shechem whatever they felt like doing. They were not afraid at all of the inhabitants of that city whose male population they had killed only a year or two earlier. They had complete confidence in G’d‘s protection. The Canaanite population in the region lived in awe of the sons of Yaakov. They had been afraid of them already at the time when they executed the male population of Schechem for being accessories to the rape of Dinah.

There are dots on the word את indicating that they went only to “pasture” themselves. Rashi means that if there were no dots on את, it would be connected to צאן, and mean “to pasture the sheep.” But now that it has dots, it is as if the את was not written at all. Consequently, לרעות is not connected to the next word, and means: “They went to pasture.” I.e., to pasture themselves. And צאן אביהם בשכם is a separate statement. But if את was completely omitted from the verse, it would not prove the point. Surely we could still say it means “to pasture themselves,” but it would be more logical to say that the words are connected, and form one statement. Thus, although the את would be omitted, we would say it is an abbreviated verse. But now that את is written, and it has dots, it is considered as erased. This indicates that the words are not connected; they are rather two statements. Otherwise, why does it have dots?
