Exodus 35:1-3

Wycliffe Bible

35 Therefore when all the company of the sons of Israel was gathered (together), Moses said to them, These things it be, which the Lord commanded to be done.

² Six days ye shall do work, the seventh day shall be holy to you, the sabbath and the rest of the Lord; he that doeth work in the sabbath shall be slain. (For six days ye shall do work, but the seventh day shall be holy to you, yea, the sabbath of rest, holy to the Lord; he who doeth work on the sabbath shall be put to death.)

³ Ye shall not kindle fire in all your dwelling places by the sabbath day. (Ye shall not kindle a fire in any of your dwellings on the sabbath day.)
