Exodus 31:13-16 Speak you also to the children of Israel, saying, Truly my sabbaths you shall keep: for it is a sign between me and you throughout your generations; that you may know that I am the LORD that does sanctify you.

AKJV⁽ⁱ⁾ ¹³ Speak you also to the children of Israel, saying, Truly my sabbaths you shall keep: for it is a sign between me and you throughout your generations; that you may know that I am the LORD that does sanctify you. ¹⁴ You shall keep the sabbath therefore; for it is holy to you: every one that defiles it shall surely be put to death: for whoever does any work therein, that soul shall be cut off from among his people. ¹⁵ Six days may work be done; but in the seventh is the sabbath of rest, holy to the LORD: whoever does any work in the sabbath day, he shall surely be put to death. ¹⁶ Why the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant.
