Here it stands at the head of all the feasts given in this marvelous chapter, in which we have foreshadowed the entire history of God's dealings with His people Israel. The Sabbath is the expression of God's eternal rest, into which it is His purpose yet to bring His people, when all their toils and sorrows, their trials and tribulations, shall have passed away--that blessed "Sabbath-keeping [σαββατισμός]" which "remaineth for the people of God." In various ways He sought to keep this glorious rest before the hearts of His people; the seventh day, the seventh year, the year of jubilee--all these lovely sabbatic seasons were designed to set forth that blessed time when Israel shall be gathered back to their own beloved land, when the Sabbath shall be kept, in all its deep, divine blessedness, as it never has been kept yet. And this leads us, naturally, to the second point in connection with the Sabbath, namely, its permanency. This is plainly proved by such expressions as, "perpetual," "a sign forever," "throughout your generations." Such words would never be applied to any merely temporary institution. True it is, alas! that Israel never really kept the Sabbath according to God; they never understood its meaning, never entered into its blessedness, never drank into its spirit. They made it a badge of their own righteousness; they boasted in it as a national institution, and used it for self-exaltation; but they never celebrated it in communion with God. We speak of the nation as a whole. We doubt not there were precious souls who, in secret, enjoyed the Sabbath, and entered into the thoughts of God about it; but as a nation, Israel never kept the Sabbath according to God. Hear what Isaiah says, "Bring no more vain oblations; incense is an abomination unto Me; the new moons and _Sabbaths_, the calling of assemblies, I cannot away with; it is iniquity, even the solemn meeting." (Chap. i. 13.)
