Exodus 31:12

The penal law of the Sabbath. Exodus 35:2-3. In the fourth commandment the injunction to observe the seventh day is addressed to the conscience of the people (see Exodus 20:8 note): in this place, the object is to declare an infraction of the commandment to be a capital offence. The two passages stand in a relation to each other similar to that between Leviticus 18, Leviticus 19, and Leviticus 20. It seems likely that the penal edict was especially introduced as a caution in reference to the construction of the tabernacle, lest the people, in their zeal to carry on the work, should be tempted to break the divine law for the observance of the day.
