Sabbath, a perpetual covenant
Exodus 31:12-17 And the Lord spoke to Moses, saying, Do thou also charge the children of Israel, saying, Take heed and keep My sabbaths; for they are a sign with Me and among you throughout your generations, that ye may know that I am the Lord that sanctifies you. And ye shall keep the sabbaths, because this is holy to the Lord for you; he that profanes it shall surely be put to death: every one who shall do a work on it, that soul shall be destroyed from the midst of his people. Six days thou shalt do works, but the seventh day is the Sabbath, a holy rest to the Lord; every one who shall do a work on the seventh day shall be put to death. And the children of Israel shall keep the Sabbaths, to observe them throughout their generations. It is a perpetual covenant with Me and the children of Israel, it is a perpetual sign with Me; for in six days the Lord made the Heaven and the Earth, and on the seventh day He ceased, and rested.LXX
