Leviticus

And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.

Remember the sabbath day, to keep it holy.

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

And he said unto them, This is that which the Lord hath said, To morrow is the rest of the holy sabbath unto the Lord: bake that which ye will bake to day, and seethe that ye will seethe; and that which remaineth over lay up for you to be kept until the morning.

And if the people of the land bring ware or any victuals on the sabbath day to sell, that we would not buy it of them on the sabbath, or on the holy day: and that we would leave the seventh year, and the exaction of every debt.
