The law of Moses laid a great deal of stress upon the sabbath, the sanctification of which was the earliest and most ancient of all divine institutions, designed for the keeping up of the knowledge and worship of the Creator among men; that law not only revived the observance of the weekly sabbath, but, for the further advancement of the honour of them, added the institution of a sabbatical year: In the seventh year shall be a sabbath of rest unto the land, Lev 25:4. And hence the Jews collect that vulgar tradition that after the world has stood six thousand years (a thousand years being to God as one day) it shall cease, and the eternal sabbath shall succeed - a weak foundation on which to build the fixing of that day and hour which it is God's prerogative to know. This sabbatical year began in September, at the end of harvest, the seventh month of their ecclesiastical year: and the law was, 1. That at the seed-time, which immediately followed the end of their in-gathering, they should sow no corn in their land, and that they should not in the spring dress their vineyards, and consequently that they should not expect either harvest or vintage the next year. 2. That what their ground did produce of itself they should not claim any property or use in, otherwise than from hand to mouth, but leave it for the poor, servants, strangers, and cattle, Lev 25:5-7. It must be a sabbath of rest to the land; they must neither do any work about it, nor expect any fruit from it; all annual labours must be intermitted in the seventh year, as much as daily labours on the seventh day. The Jews say they "began not to reckon for the sabbatical year till they had completed the conquest of Canaan, which was in the eighth year of Joshua; the seventh year after that was the first sabbatical year, and so the fiftieth year was the jubilee." This year there was to be a general release of debts (Deu 15:1, Deu 15:2), and a public reading of the law in the feast (Deu 31:10, Deu 31:11), to make it the more solemn. Now, (1.) God would hereby show them that he was their landlord, and that they were tenants at will under him. Landlords are wont to stipulate with their tenants when they shall break up their ground, how long they shall till it, and when they shall let it rest: God would thus give, grant, and convey, that good land to them, under such provisos and limitations as should let them know that they were not proprietors, but dependents on their Lord. (2.) It was a kindness to their land to let it rest sometimes, and would keep it in heart (as our husbandmen express it) for posterity, whose satisfaction God would have them to consult, and not to use the ground as if it were designed only for one age. (3.) When they were thus for a whole year taken off from all country business, they would have the more leisure to attend the exercises of religion, and to get the knowledge of God and his law. (4.) They were hereby taught to be charitable and generous, and not to engross all to themselves, but to be willing that others should share with them in the gifts of God's bounty, which the earth brought forth of itself. (5.) They were brought to live in a constant dependence upon the divine providence, finding that, as man lives not by bread alone, so he has bread, not by his own industry alone, but, if God pleases, by the word of blessing from the mouth of God, without any care or pains of man, Mat 4:4. (6.) They were reminded of the easy life man lived in paradise, when he ate of every good thing, not, as since, in the sweat of his face. Labour and toil came in with sin. (7.) They were taught to consider how the poor lived, that did neither sow nor reap, even by the blessing of God upon a little. (8.) This year of rest typified the spiritual rest which all believers enter into through Christ, our true Noah, who giveth us comfort and rest concerning our work, and the toil of our hands, because of the ground which the Lord hath cursed, Gen 5:29. Through him we are eased of the burden of worldly care and labour, both being sanctified and sweetened to us, and we are enabled and encouraged to live by faith. And, as the fruits of this sabbath of the land were enjoyed in common, so the salvation wrought out by Christ is a common salvation; and this sabbatical year seems to have been revived in the Christian church, when the believers had all things common, Act 2:44.

The land keep a Sabbath - See this ordinance explained, Exo 23:11 (note). It may be asked here: if it required all the annual produce of the field to support the inhabitants, how could the people be nourished the seventh year, when no produce was received from the fields? To this it may be answered, that God sent his blessing in an especial manner on the sixth year, (see Lev 25:21, Lev 25:22), and it brought forth fruit for three years. How astonishing and convincing was this miracle! Could there possibly be any deception here? No! The miracle speaks for itself, proves the Divine authenticity of the law, and takes every prop and stay from the system that wishes to convict the Mosaic ordinances of imposture. See Exo 23:11. It is evident from this that the Mosaic law must have had a Divine origin, as no man in his senses, without God's authority, could have made such an ordinance as this; for the sixth year, from its promulgation, would have amply refuted his pretensions to a Divine mission.

Speak unto the children of Israel, and say unto them,.... What follows, being what the whole body of the people would be under obligation to observe, and therefore must be delivered to them all, at least to the heads and elders of the people, and by them to the rest:

when ye come into the land which I give you; the land of Canaan, and until they came thither, the following law concerning the sabbatical year could not take place; and as Maimonides (i) says, it was only used in the land of Israel, and no where else, according to this text, and that both before and after the temple was built:

then shall the land keep a sabbath unto the Lord; a rest from tillage, as it is afterwards explained; and this being according to the will of God, when observed would be to his honour and glory, and show that he was the proprietor of the land; and that the Israelites held it under him by this tenure, that every seventh year they should let it rest, which would be for the benefit of the land, and preserve it from being impoverished by continual usage and hereby they might learn to depend on the providence of God, and to observe that all increase is from him; and to consider the straits and difficulties the poor live in continually, as they in this seventh year; and by this means they would be at leisure to have an opportunity of reading the law, as they did at this time, Deu 31:10; and of meditating upon it, and of giving themselves up to religious exercises, as well as by it they might be led to the typical use of to look for and expect that sabbatism or rest, which remains for the people of God. And now this law did not take place as soon as they came into the land, for it was to be sown six years, and then was the year of rest; and indeed not till after Joshua had subdued the whole land, which was seven years a doing; nor till they were quite settled, and it was divided among them, and every man had his field and vineyard apart, which this law supposes; wherefore the Jewish writers (k) say, they were not bound to tithes until the fourteenth year, and from thence they began to reckon the sabbatical year; and the twenty first year they made a sabbatical year, and the sixty fourth a jubilee, which they make to be the first that were kept: and they reckoned this year to commence, not on the first of Nisan or March, which was the beginning of the year for ecclesiastical things, but on the first of Tisri or September, when the harvest and all the fruits of the earth were gathered in; and when on other years they used to proceed to sowing the next month, but were forbid on this; and so it is said in the Misnah (l), the first of Tisri is the beginning of the year for the sabbatical and jubilee years.
