31:16 It was to be observed throughout their generations, in every age, for a perpetual covenant - This was to be one of the most lasting tokens of the covenant between God and Israel.
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.
