okay.
there are more to it, i'll just post the verse now, since you want it from the Bible.
Exodus 16
29 See, for the Lord hath given you the Sabbath; therefore He giveth you on the sixth day the bread for two days. Abide ye every man in his place. Let no man go out of his place on the seventh day.”
(so stay at your house all day)
Exodus 35
3 Ye shall kindle no fire throughout your habitations upon the Sabbath day.”
(fire back then, I supposed a replacement for electricity, so no electricity all day)
Deuteronomy 5
14 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, nor thy manservant, nor thy maidservant, nor thine ox, nor thine ass, nor any of thy cattle, nor thy stranger that is within thy gates, that thy manservant and thy maidservant may rest as well as thou.
(no work in your household may be done)
Exodus 31
15 Six days may work be done, but on the seventh is the Sabbath of rest, holy to the Lord. Whosoever doeth any work on the Sabbath day, he shall surely be put to death.
Numbers 15
32 And while the children of Israel were in the wilderness, they found a man who gathered sticks upon the Sabbath day.
33 And those who found him gathering sticks brought him unto Moses and Aaron and unto all the congregation.
34 And they put him under guard, because it was not declared what should be done to him.
35 And the Lord said unto Moses, “The man shall be surely put to death. All the congregation shall stone him with stones outside the camp.”
(any violators shall be put to death)
agreeing with me so far?
