וַיַּ֤רְא מְנֻחָה֙ כִּ֣י ט֔וֹב וְאֶת־הָאָ֖רֶץ כִּ֣י נָעֵ֑מָה וַיֵּ֤ט שִׁכְמוֹ֙ לִסְבֹּ֔ל וַיְהִ֖י לְמַס־עֹבֵֽד׃ (ס)
Ибо он увидел место отдыха, где было хорошо, и землю, в которой было приятно; И он склонил плечо, чтобы нести, И стал слугой под заданием

a day of rest, idleness and amusement -- Three disgraces each worse than the other. The first person who hates hard work, and after a bit of strain, already wants to rest. He does not realize that a "man was born to toil" (Iyov 5:7),and according to the greatness of the purpose will be the greatness of the necessary strain to attain it, as written "[he saw that the rest (in the afterlife) was good, and the land that it was pleasant;] and bowed his shoulder to bear" (Bereishis 49:15). Worse than this person, is a lazy man who loves idleness, and does not desire any work, as written "A sluggard buries his hand in the dish; he will not even bring it back to his mouth" (Mishlei 19:24). Even worse than both of these, some people hate idleness and are energetic. However, all of their toil is in futilities and foolishness, such as playing with dice or the like. Hence, this person sometimes makes "a day of rest", to rest from the feeling of strain of the previous days. Sometimes, even though he does not feel any strain in his body, he desires idleness, and sometime he made that day a day of amusement, to amuse himself with futile toil.

AND I WILL DELIVER YOU FROM THEIR BONDAGE. The Egyptians will no longer rule over them at all, nor will they subject them to be a servant under tribute40Genesis 49:15. wherever they live.

“…when he tells them: “This is menuhah, rest….”28Isa. 28:12. (It was known to the people of Israel that the Torah was called “rest” from Jacob’s blessing to Issachar: “He saw that rest was good and that the land was pleasant, yet he bent his shoulder to bear, and he became an indentured laborer.”29Gen. 49:15. As it has already been explained in the [Midrash Rabbah],30Midrash Rabbah on the Torah portion Vayyehi, Gen. 98:17. the word “rest” refers to the Torah. The subject of this verse is that it was the custom of the tribes of Israel to set apart a fund [to support] the soldiers and [cover] their expenses. It is known that men of valor [due to their involvement with military affairs] cannot immerse themselves in the study of Torah, nor are they able to settle the Land [of Israel]. Therefore, for this reason, Jacob blessed Issachar, for he [Issachar], saw that the “rest” of the Torah was good, and that the land was pleasant. [Jacob] did not wish to [bless Issachar] with valorous men, for they loved “to rest between the boundaries,”31Gen. 49:14. The full verse is, “Issachar is a strong-boned donkey; he rests between the boundaries.” See Part 1, chapter 18 for an explanation of this verse. [that is, to sit and toil in the study of Torah day and night].
