25:1-7 All labour was to cease in the seventh year, as much as daily labour on the seventh day. These statues tell us to beware of covetousness, for a man's life consists not in the abundance of his possessions. We are to exercise willing dependence on God's providence for our support; to consider ourselves the Lord's tenants or stewards, and to use our possessions accordingly. This year of rest typified the spiritual rest which all believers enter into through Christ. Through Him we are eased of the burden of wordly care and labour, both being sanctified and sweetened to us; and we are enabled and encouraged to live by faith.
2-4. When ye come into the land which I give you—It has been questioned on what year, after the occupation of Canaan, the sabbatic year began to be observed. Some think it was the seventh year after their entrance. But others, considering that as the first six years were spent in the conquest and division of the land (Jos 5:12), and that the sabbatical year was to be observed after six years of agriculture, maintain that the observance did not commence till the fourteenth year.
the land keep a sabbath unto the Lord—This was a very peculiar arrangement. Not only all agricultural processes were to be intermitted every seventh year, but the cultivators had no right to the soil. It lay entirely fallow, and its spontaneous produce was the common property of the poor and the stranger, the cattle and game. This year of rest was to invigorate the productive powers of the land, as the weekly Sabbath was a refreshment to men and cattle. It commenced immediately after the feast of ingathering, and it was calculated to teach the people, in a remarkable manner, the reality of the presence and providential power of God.
