Thanks for the input!All one really needs to do is read the context...
Exo 35:1 And Moses gathered all the congregation of the children of Israel together, and said unto them, These are the words which the LORD hath commanded, that ye should do them.
Exo 35:2 Six days shall work be done, but on the seventh day there shall be to you an holy day, a sabbath of rest to the LORD: whosoever doeth work therein shall be put to death.
Exo 35:3 Ye shall kindle no fire throughout your habitations upon the sabbath day.
Exo 35:4 And Moses spake unto all the congregation of the children of Israel, saying, This is the thing which the LORD commanded, saying,
Exo 35:5 Take ye from among you an offering unto the LORD: whosoever is of a willing heart, let him bring it, an offering of the LORD; gold, and silver, and brass,
Exo 35:6 And blue, and purple, and scarlet, and fine linen, and goats' hair,
Exo 35:7 And rams' skins dyed red, and badgers' skins, and shittim wood,
Exo 35:8 And oil for the light, and spices for anointing oil, and for the sweet incense,
Exo 35:9 And onyx stones, and stones to be set for the ephod, and for the breastplate.
and the instructions go on here about BUILDING the Tabernacle.
Let's read this passage in context with understanding...
The first thing God reminds the people of is that one does not do work, one's customary employment, on the Sabbath. Neither does one do home repairs, build fence or make hay.
Now that we God has established the very first principle, that work is not done on the Sabbath, He continues with the subject at hand, making the Tabernacle.
First thing to remember is that even though you are making the Tabernacle of God, you do not do work on the Sabbath. OK, we got this. Now let's look at the fire...
John Gill (the master of run-on sentences) writes this...
Ye shall kindle no fire throughout your habitations upon the sabbath day. This law seems to be a temporary one, and not to be continued, nor is it said to be throughout their generations as elsewhere, where the law of the sabbath is given or repeated; it is to be restrained to the building of the tabernacle, and while that was about, to which it is prefaced; and it is designed to prevent all public or private working on the sabbath day, in anything belonging to that; having no fire to heat their tools or melt their metal, or do any thing for which that was necessary; for it can hardly be thought that this is to be taken in the strictest sense, as an entire prohibition of kindling a fire and the use of it on that day, which is so absolutely useful, and needful in various cases, and where acts of mercy and necessity require it; as in cold seasons of the year, for the warming and comforting of persons who otherwise would be unfit for religious exercises, and on the account of infants and aged persons, who could not subsist without it; and in cases of sickness, and various disorders which necessarily require it; and even for the preparation of food, which must be had on that day as on others, the sabbath being not a fast, but rather a festival, as it is with the Jews;
Matthew Henry has this in his commentary...
III. He begins with the law of the sabbath, because that was much insisted on in the instructions he had received (Exo_35:2, Exo_35:3): Six days shall work be done, work for the tabernacle, the work of the day that was now to be done in its day; and they had little else to do here in the wilderness, where they had neither husbandry nor merchandise, neither food to get nor clothes to make: but on the seventh day you must not strike a stroke, no, not at the tabernacle-work; the honour of the sabbath was above that of the sanctuary, more ancient and more lasting; that must be to you a holy day, devoted to God, and not be spent in common business. It is a sabbath of rest. It is a sabbath of sabbaths (so some read it), more honourable and excellent than any of the other feasts, and should survive them all. A sabbath of sabbatism, so others read it, being typical of that sabbatism or rest, both spiritual and eternal, which remains for the people of God, Heb_4:9. It is a sabbath of rest, that is, in which a rest from all worldly labour must be very carefully and strictly observed. It is a sabbath and a little sabbath, so some of the Jews would have it
A good possible interpretation, that this law was only to be used during the building of the tabernacle... though I'm not sure I agree with Gill about "as in cold seasons of the year...". Does it get cold enough in that area to need a fire?
