Isaiah 58

13 If you make sure you don’t break*58:13. "If you make sure you don’t break," literally, "If you keep your foot from." the Sabbath by doing whatever you please on my holy day, if you say the Sabbath brings you pleasure and the Lord’s day is to be honored, and if you honor it by leaving aside your own ways, by not doing whatever you please, and by avoiding chatting about ordinary things,*58:13. "chatting about ordinary things": the Hebrew is literally "the speaking of a word," but clearly this does not mean that nothing at all is to be said on the Sabbath, as this would preclude worship services. What seems to be the concept is that conversation of little value is to be avoided. 14 then you’ll find the Lord is the one who truly makes you happy, and I will give you high positions on the earth and give you what I promised to Jacob, your forefather. I, the Lord, have spoken.
