Exodus 31:13-15

Amplified Bible, Classic Edition

¹³ Say to the Israelites, Truly you shall keep My Sabbaths, for it is a sign between Me and you throughout your generations, that you may know that I, the Lord, sanctify you [set you apart for Myself].

¹⁴ You shall keep the Sabbath therefore, for it is holy to you; everyone who profanes it shall surely be put to death; for whoever does work on the Sabbath shall be cut off from among his people.

¹⁵ Six days may work be done, but the seventh is the Sabbath of rest, sacred to the Lord; whoever does work on the Sabbath day shall surely be put to death.
