The institution of the Sabbath and the scrupulous observance of it were, for Israel, and are still for all believers in Divine religion, most important means of maintaining unity in the faith. Now that many causes interfere with the simultaneous exhibition of regard for other symbols of Christian belief, the day of rest and worship gives a universal opportunity which it would be fatal to neglect. It has the advantage of beginning to claim men on the ground where religion first appeals to them, that of God's care for their temporal well-being. Those with whom religious feeling is quite elementary must see that a boon of incalculable value is offered in this recurring refreshment to the wearied body and strained mind. And with progress in religious culture the benefit of the day of rest is found to advance. The opportunities of worship, of religious meditation and service, which it brings will be esteemed as the value of Christian fellowship, the importance of Christian knowledge, and the duty of Christian endeavour are successively understood. On all these grounds the Sabbath, or Lord's Day, is for modern religion, as for that of the old covenant, a great declaration, a means of unity and development which the spiritual will earnestly uphold. Let it fail, and distinction between religious and non-religious will be without a sign. No doubt the reality is more by far than the symbol. Yet fellowship, for which in many cases the Sabbath alone gives opportunity, is far more than a symbol; and unity requires an outward manifestation. Nothing could be more perilous to the religious life of our people than the tendency, shown by many who profess Christianity and sanctioned by some of its teachers, to make the Sabbath a day of self-pleasing, of mere individualism, and incoherent secularity. 3. THE MEMORIAL TASSELS.--The unique sumptuary law with which the chapter closes may be regarded as a sequence of the Sabbath-breaker's conviction. That Israelites might never be without a reminder of their duty, and of the Divine laws they were scrupulously to observe, these tassels with a band of blue were to be constantly worn. It appears to us singular that men should be expected to pay heed to such mementoes as these. We are apt to say, If the laws of God were not in their hearts, the _zizith_ would scarcely make them more attentive; and if they had the laws in their hearts, they would need no memorials of obligation. But the ornament was something more than a reminder of duty. It was a badge of honour, and became more so as the Israelites understood their high position among the peoples. The _zizith_ would be like an order, a mark of rank; or like the uniform of his regiment which to the good soldier recalls its history. The Hebrew would have to live up to his duty as signified by these attachments of his dress.
