Exodus 31:15-17 Six days will work be done, but on the seventh day is a Sabbath of solemn rest, holy to Jehovah. Whoever does any work on the Sabbath day, he will surely be put to death.

MLV⁽ⁱ⁾ ¹⁵ Six days will work be done, but on the seventh day is a Sabbath of solemn rest, holy to Jehovah. Whoever does any work on the Sabbath day, he will surely be put to death. ¹⁶ Therefore the sons of Israel will keep the Sabbath, to observe the Sabbath throughout their genealogy, for a everlasting covenant. ¹⁷ It is a sign between me and the sons of Israel everlasting. For in six days Jehovah made heaven and earth and on the seventh day he rested and was refreshed.
