Exodus 31:13-17

LITV(i) 13 And you speak to the sons of Israel, saying, You shall surely keep My sabbaths; for it is a sign between Me and you for your generation; to know that I am Jehovah your sanctifier. 14 And you shall keep the Sabbath, for it is holy for you; the profaners of it surely shall be put to death; for everyone doing work in it, that soul shall be cut off from the midst of his people. 15 Work may be done six days, and on the seventh day is a sabbath of rest, holy to Jehovah; everyone doing work on the Sabbath day surely shall be put to death. 16 And the sons of Israel shall observe the Sabbath, to do the Sabbath for their generations; it is a never ending covenant. 17 It is a sign forever between Me and the sons of Israel; for in six days Jehovah made the heavens and the earth, and on the seventh day He rested and was refreshed.
