Exodus 31:15-17

Complete Jewish Bible

¹⁵ On six days work will get done; but the seventh day is Shabbat, for complete rest, set apart for Adonai. Whoever does any work on the day of Shabbat must be put to death. ¹⁶ The people of Isra’el are to keep the Shabbat, to observe Shabbat through all their generations as a perpetual covenant. ¹⁷ It is a sign between me and the people of Isra’el forever; for in six days Adonai made heaven and earth, but on the seventh day he stopped working and rested.’”
