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 Gen 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 Exo 20:11.
