13 Say to the children of Israel that they are to keep my Sabbaths; for the Sabbath day is a sign between me and you through all your generations; so that you may see that I am the Lord who makes you holy. 14 So you are to keep the Sabbath as a holy day; and anyone not honouring it will certainly be put to death: whoever does any work on that day will be cut off from his people.
Matthew Henry's Commentary on Exodus 31:13-14
Commentary on Exodus 31:12-17
(Read Exodus 31:12-17)
Orders were now given that a tabernacle should be set up for the service of God. But they must not think that the nature of the work, and the haste that was required, would justify them in working at it on sabbath days. The Hebrew word /shabath/ signifies rest, or ceasing from labour. The thing signified by the sabbath is that rest in glory which remains for the people of God; therefore the moral obligation of the sabbath must continue, till time is swallowed up in eternity.
