- The Book of Isaiah (Hebrew: ספר ישעיהו ) is the first of the Latter Prophets in the Hebrew Bible and the first of the major prophets in the Christian Old Testament. It is identified by a superscription as the words of the 8th-century BCE prophet Isaiah, but there is evidence that much of it was composed during the Babylonian captivity and later.
but the seventh day is a sabbath to the LORD your God. On it you shall not do any work, neither you, nor your son or daughter, nor your male or female servant, nor your animals, nor any foreigner residing in your towns.
Exodus 20:10 NIV
