Herewith now begins the fourth and last division of this chapter (vv. 30-37), with a repetition of the injunction to keep the Sabbaths of the Lord, and reverence His sanctuary. The emphasis on this command, shown by its repetition in this chapter, and the very prominent place which it occupies both in the law and the prophets, certainly suggests that in the mind of God, reverence for the Sabbath and for the place where God is worshipped, has much to do with the promotion of holiness of life, and the maintenance of a high degree of domestic and social morality. Nor is it difficult to see why this should be so. For however the day of holy rest may be kept, and the place of Divine worship be regarded with only an outward reverence by many, yet the fact cannot be disputed, that the observance of a weekly sabbatic rest from ordinary secular occupations, and the maintenance of a spirit of reverence for sacred places or for sacred times, has, and must have, a certain and most happy tendency to keep the God of the Sabbath and the God of the sanctuary before the mind of men, and thus imposes an effective check upon unrestrained godlessness and reckless excesses of iniquity. The diverse condition of things in various parts of modern Christendom, as related to the more or less careful observance of the weekly religious rest, is full of both instruction and warning to any candid mind upon this subject. There is no restraint on immorality like the frequent remembrance of God and the spirit of reverence for Him.
