'Sabbath' in the Bible

Blessed is the one who does this, and the person that holds it fast, who observes the Sabbath without profaning it, and restrains his hands from practicing any evil.

"Also, the foreigners who join themselves to the LORD, to minister to him, to love the name of the LORD, to be his servants, and to bless the LORD'S name, observing the Sabbath without profaning it, and who hold fast my covenant

"If you keep your feet from trampling the Sabbath, from pursuing your own interests on my holy day, if you call the Sabbath a delight and the LORD's holy day honorable; and if you honor it by not going your own ways and seeking your own pleasure or speaking merely idle words,

And from New Moon to New Moon, and from Sabbath to Sabbath, all humanity will come to worship before me," says the LORD.
