'Sabbath day' in the Bible

Remember the sabbath day, to hallow it:

For, in six days, did Yahweh make the heavens and the earth, and the sea - and all that in them is, and rested on the seventh day, - for this cause, Yahweh blessed the sabbath day and hallowed it.

Six days, shall work be done, but on the seventh day, is a holy sabbath-keeping of rest unto Yahweh, - whosoever doeth work on the sabbath day, shall be, surely put to death.

Ye shall not kindle a fire, in any of your dwellings, - on the sabbath day.
