Exodus 35:2

Six days shall work be done: but the seventh day is the sabbath of rest, an holy convocation; ye shall do no work therein: it is the sabbath of the LORD in all your dwellings.

Six days thou shalt work, but on the seventh day thou shalt rest: in earing time and in harvest thou shalt rest.

Six days thou shalt do thy work, and on the seventh day thou shalt rest: that thine ox and thine ass may rest, and the son of thy handmaid, and the stranger, may be refreshed.

And therefore did the Jews persecute Jesus, and sought to slay him, because he had done these things on the sabbath day.
