Exodus 35:1-3

1Then Moses assembled all the congregation of the sons of Israel, and said to them, “1These are the things that the Lord has commanded you to 2do:

2“3For six days work may be done, but on the seventh day you shall have a holy day, 4a sabbath of complete rest to the Lord; 5whoever does any work on it shall be put to death. 36You shall not kindle a fire in any of your dwellings on the sabbath day.”
