Midrash sobre Isaías 58:14

A Question.⁹Sections 2 and 3 of “In the Beginning” and the fourth section of “Noah” were taken from the She’iltot of R. Ahai, a distinguished Babylonian scholar who left Palestine in the middle of the eighth century. See Jewish Encyclopedia 1:279. Why are the House of Israel required to rest on the Sabbath day? They do so because when the Holy One, blessed be He, created His world, He completed the work of creation in six days and rested on the Sabbath day; He blessed that day and sanctified it, just as one who completes the building of his home commemorates the event with a celebration called a hilul (a ceremony of dedication upon the completion of a home), as it is written: And on the seventh day God finished (va-yikhal) His work (Gen. 2:2). Furthermore, the Merciful One declares: “Rest on the Sabbath day, just as I rested upon it,” as it is said: And He rested on the seventh day, wherefore the Lord blessed the Sabbath day and hallowed it (Exod. 20:11).

Our sages declared: Call the Sabbath a delight indicates that you should not eat on the Sabbath day as you do on a weekday, rather you should delight in it. Of its reward it is written: Then thou shalt delight in the Lord.

(Deut. 33:4:) MOSES CHARGED US WITH TORAH, AS THE HERITAGE FOR THE CONGREGATION OF ISRAEL. It is a heritage for all the congregations of Jacob, for whoever engages in it for its own sake is worthy of the inheritance of Jacob, as stated (in Is. 58:14): THEN YOU SHALL TAKE DELIGHT IN THE LORD…, AND I WILL FEED YOU THE INHERITANCE OF YOUR FATHER JACOB.
