Isaiah 58:13: “Im tashiv me’Shabbat raglechah asot chah-fatzechah beyom kadshi, V-karat la’Shabbat oneg likdosh Hashem mechubad. Vchiybadito ma-asot derachecha mimtzoh cheftzecha v-daber davar. Az titanag al Hashem vehirkavtechah al bamotai aretz v’ha’alticha nachalt Ya’akov aviycha ki pi Adoshem Yidaber.”
“If you restrain your foot, because it is the Sabbath; refrain from accomplishing your own needs on my holy day. If you proclaim the Sabbath ‘a delight’ and the holy day of Hashem honored and you honor it by not engaging in your own affairs from seeking your own needs or discussing the forbidden – hence you will delight in Hashem, and I will provide you the heritage of your forefather Jacob, for the mouth of Hashem has spoken.”
The Talmud states (Shabbat 118b) that Rav Yehuda said in Rav’s name: He who delights in the Shabbat is granted his heart’s desires.
