The LORD spoke to Moshe, saying,
"Speak also to the children of Yisra'el, saying, 'Most assuredly you shall keep my Shabbatot: for it is a sign between me and you throughout your generations; that you may know that I am the LORD who sanctifies you.
You shall keep the Shabbat therefore; for it is holy to you. Everyone who profanes it shall surely be put to death; for whoever does any work therein, that soul shall be cut off from among his people.
Six days shall work be done, but on the seventh day is a Shabbat of solemn rest, holy to the LORD. Whoever does any work on the day of Shabbat shall surely be put to death.
Therefore the children of Yisra'el shall keep the Shabbat, to observe the Shabbat throughout their generations, for a perpetual covenant.
It is a sign between me and the children of Yisra'el forever; for in six days the LORD made heaven and eretz, and on the seventh day he rested, and was refreshed.'"
He gave to Moshe, when he finished speaking with him on Mount Sinai, the two tablets of the testimony, stone tablets, written with God's finger.
