Exodus 20: 8 Remember the sabbath day, to keep it holy. 9 Six days shalt thou labor, and do all thy work.
Exodus 20:10 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, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates. 11 For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day, and hallowed it.
The following therefore is the unadulterated word of God on the matter, and we should let the Bible speak for itself. As we read, remember that Jesus is The God of both the Old and New Testaments, so if there are any lingering questions, the one will shed light on the other. Numbers 15:32 And while the children of Israel were in the wilderness, they found a man that gathered sticks upon the sabbath day.
Numbers 15:33 And they that found him gathering sticks brought him unto Moses and Aaron, and unto all the congregation. Question: Why was this man gathering sticks on the Sabbath? He was doing so to kindle a fire, but it was not necessary because at that time, Christ, the pillar of cloud by day, and the pillar of fire by night took care of regulating the temperature, so that they did not suffer from any extreme cold or heat.
Numbers 15:34 And they put him in ward, because it was not declared what should be done to him.
May The Lord add His blessing to the study of His word. God bless!
