Was refreshed - Literally, "he took breath". Compare Exodus 23:12; 2 Samuel 16:14. The application of the word to the Creator, which occurs nowhere else, is remarkable.

Rested, and was refreshed - God, in condescension to human weakness, applies to himself here what belongs to man. If a man religiously rests on the Sabbath, both his body and soul shall be refreshed; he shall acquire new light and life.

It is a sign between me and the children of Israel for ever,.... In like sense as the land of Canaan was given them for an everlasting possession; and the covenant of circumcision, and the ordinance of the passover, and the fast on the day of atonement, were for ever; that is, unto the end of the Jewish world and state, at the coming of Christ, when a new world and state of things began, see Genesis 17:8.

for in six days the Lord made heaven and earth, and on the seventh day he rested, and was refreshed; which is to be understood figuratively after the manner of men, who ceasing from toil and labour find rest and refreshment; but not really and properly, for as not labour, and weariness, and fatigue, so neither rest nor refreshment can be properly said of God; but this denotes his cessation from the works of creation, though not of providence, and of the delight and pleasure he takes in a view of them; this is observed, not as the foundation of this law, and the reason of its being made, but as an illustration of it, and as an argument, showing the reasonableness of it, and the similarity of it with what God himself had done, and therefore the enjoining of it could not reasonably be objected to. See Gill on Exodus 20:11.

It is a sign between me and the children of Israel for ever: for in six days the LORD made heaven and earth, and on the seventh day he {h} rested, and was refreshed.

(h) From creating his creatures, but not from governing and preserving them.

31:17 On the seventh day he rested - And as the work of creation is worthy to be thus commemorated, so the great Creator is worthy to be thus imitated, by a holy rest the seventh day.

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.
