Isaia 58,13+14

If you hold back your foot on Shabbat from pursuing your own interests on my holy day; if you call Shabbat a delight, ADONAI’s holy day, worth honoring; then honor it by not doing your usual things or pursuing your interests or speaking about them. If you do, you will find delight in ADONAI – I will make you ride on the heights of the land and feed you with the heritage of your ancestor Yakov, for the mouth of ADONAI has spoken.
