Shemoth (Exo) 20:8-11
“Remember the Sabbath day, to set it apart. Six days you labour, and shall do all your work, but the seventh day is a Sabbath1 of יהוה your Elohim. You do not do any work – you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who is within your gates. For in six days יהוה made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore יהוה blessed the Sabbath day and set it apart."
Wayyiqra (Lev) 23:2-3
“Speak to the children of Yisra’ĕl, and say to them, ‘The appointed times of יהוה, which you are to proclaim as set-apart gatherings, My appointed times, are these:
‘Six days work is done, but the seventh day is a Sabbath of rest, a set-apart gathering. You do no work, it is a Sabbath to יהוה in all your dwellings. "
“If you do turn back your foot from the Sabbath, from doing your pleasure on My set-apart day, and shall call the Sabbath ‘a delight,’ the set-apart day of יהוה ‘esteemed,’ and shall esteem it, not doing your own ways, nor finding your own pleasure, nor speaking your own words,
Isa 58:14 then you shall delight yourself in יהוה. And I shall cause you to ride on the heights of the earth, and feed you with the inheritance of Yaʽaqoḇ your father. For the mouth of יהוה has spoken!”
