Exodus 31:14-17 Keep the sabbath, therefore; for it is holy unto you; every one that profaneth it shall certainly be put to death: yea, whoever doeth work on it, that soul shall be cut off from among his peoples.

Darby⁽ⁱ⁾ ¹⁴ Keep the sabbath, therefore; for it is holy unto you; every one that profaneth it shall certainly be put to death: yea, whoever doeth work on it, that soul shall be cut off from among his peoples. ¹⁵ Six days shall work be done; but on the seventh day is the sabbath of rest, holy to Jehovah: whoever doeth work on the sabbath day shall certainly be put to death. ¹⁶ And the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations -- [it is] an everlasting covenant. ¹⁷ It shall be a sign between me and the children of Israel for ever; for [in] six days Jehovah made the heavens and the earth, and on the seventh day he rested, and was refreshed.
