15 Work shall be done for six days, but the seventh is the Sabbath of rest, holy to the Lord. Whoever does any work on the Sabbath day, he shall surely be put to death.

Matthew Henry's Commentary on Exodus 31:15

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.
