Exodus 31:14

11 and the anointing oil, and the perfume of the spices for the sanctuary; according to all that I have commanded thee -- they do.`

12 And Jehovah speaketh unto Moses, saying,

13 `And thou, speak unto the sons of Israel, saying, Only, My sabbaths ye do keep, for it [is] a sign between Me and you, to your generations, to know that I, Jehovah, am sanctifying you;

14 and ye have kept the sabbath, for it [is] holy to you, he who is polluting it is certainly put to death -- for any who doeth work in it -- that person hath even been cut off from the midst of his people.

15 `Six days is work done, and in the seventh day [is] a sabbath of holy rest to Jehovah; any who doeth work in the sabbath-day is certainly put to death,

16 and the sons of Israel have observed the sabbath; to keep the sabbath to their generations [is] a covenant age-during,

17 between Me and the sons of Israel it [is] a sign -- to the age; for six days Jehovah made the heavens and the earth, and in the seventh day He hath ceased, and is refreshed.`
