Exodus 31:13

And hallow my sabbaths; and they shall be a sign between me and you, that ye may know that I am the LORD your God.

Moreover also I gave them my sabbaths, to be a sign between me and them, that they might know that I am the LORD that sanctify them.

It is a sign between me and the children of Israel for ever: for in six days the LORD made heaven and earth, and on the seventh day he rested, and was refreshed.

Ye shall keep my sabbaths, and reverence my sanctuary: I am the LORD.

Ye shall fear every man his mother, and his father, and keep my sabbaths: I am the LORD your God.

Ye shall keep my sabbaths, and reverence my sanctuary: I am the LORD.

Remember the sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work: But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.

And madest known unto them thy holy sabbath, and commandedst them precepts, statutes, and laws, by the hand of Moses thy servant:

Speak unto the children of Israel, and say unto them, When ye come into the land which I give you, then shall the land keep a sabbath unto the LORD. keep: Heb. rest

Jude, the servant of Jesus Christ, and brother of James, to them that are sanctified by God the Father, and preserved in Jesus Christ, and called:

And the heathen shall know that I the LORD do sanctify Israel, when my sanctuary shall be in the midst of them for evermore.

And ye shall keep my statutes, and do them: I am the LORD which sanctify you.
