Exodus 34:21

“Six days you shall labor and do all your work,

“Six days you are to do your work, but on the seventh day you shall rest so that your ox and your donkey may rest, and the son of your maidservant, as well as your sojourner, may refresh themselves.

‘Six days work may be done, but on the seventh day there is a sabbath of complete rest, holy to Yahweh; whoever does any work on the sabbath day shall surely be put to death.

“Six days work may be done, but on the seventh day you shall have a holy day, a sabbath of complete rest to Yahweh; whoever does any work on it shall be put to death.

In those days I saw in Judah some who were treading wine presses on the sabbath, and bringing in sacks of grain and loading them on donkeys, as well as wine, grapes, figs and all kinds of loads, and they brought them into Jerusalem on the sabbath day. So I testified against them on the day they sold food.
