The land was to be divided by lot among the families of the Israelites when the possession of it was obtained. Numbers 26:52-56; Numbers 33:54, etc. At the end of every seventh sabbatical cycle of years, in the year of Jubilee, each field or estate that might have been alienated was to be restored to the family to which it had been originally allotted.

Leviticus 25:8

Seven sabbaths of years - seven weeks of years.

Thou shalt number seven Sabbaths of years - This seems to state that the jubilee was to be celebrated on the forty-ninth year; but in Leviticus 25:10 and Leviticus 25:11 it is said, Ye shall hallow the fiftieth year, and, A jubilee shall this fiftieth year be. Probably in this verse Moses either includes the preceding jubilee, and thus with the forty-ninth makes up the number fifty; or he speaks of proclaiming the jubilee on the forty-ninth, and celebrating it on the fiftieth year current. Some think it was celebrated on the forty-ninth year, as is stated in Leviticus 25:8; and this prevented the Sabbatical year, or seventh year of rest, from being confounded with the jubilee, which it must otherwise have been, had the celebration of this great solemnity taken place on the fiftieth year; but it is most likely that the fiftieth was the real jubilee.

And thou shalt number seven sabbaths of years unto thee,.... Or weeks of years; and there being seven days in a week, and a day being put for a year, seven weeks of years made forty nine years; the Targums of Onkelos and Jonathan, and Jarchi, interpret it seven "shemittas", or sabbatical years; and a sabbatical year being every seventh year, made the same number:

seven times seven years: or forty nine years, as follows:

and the space of the seven sabbaths of years shall be forty and nine years; just such a space of years there was between each jubilee, which, as afterwards said, was the fiftieth year; so as there were a seventh day sabbath, and a fiftieth day sabbath, the day of Pentecost, so there were a seventh year sabbath, or sabbatical year, and a fiftieth year sabbath.

The law for the Year of Jubilee refers first of all to its observance (Leviticus 25:8-12), and secondly to its effects (a) upon the possession of property (vv. 13-34), and (b) upon the personal freedom of the Israelites (vv. 35-55).

Leviticus 25:8-9

Keeping the year of jubilee. Leviticus 25:8, Leviticus 25:9. Seven Sabbaths of years - i.e., year-Sabbaths or sabbatical years, or seven times seven years, the time of seven year-Sabbaths, that is to say, 49 years - they were to count, and then at the expiration of that time to cause the trumpet of jubilee to go (sound) through the whole land on the tenth of the seventh month, i.e., the day of atonement, to proclaim the entrance of the year of jubilee. This mode of announcement was closely connected with the idea of the year itself. The blowing of trumpets, or blast of the far-sounding horn (shophar, see at Leviticus 23:24), was the signal of the descent of the Lord upon Sinai, to raise Israel to be His people, to receive them into His covenant, to unite them to Himself, and bless them through His covenant of grace (Exodus 19:13, Exodus 19:16, Exodus 19:19; Exodus 20:18). Just as the people were to come up to the mountain at the sounding of the יובל, or the voice of the shophar, to commemorate its union with the Lord, so at the expiration of the seventh sabbatical year the trumpet-blast was to announce to the covenant nation the gracious presence of its God, and the coming of the year which was to bring "liberty throughout the land to all that dwelt therein" (Leviticus 25:10), - deliverance from bondage (Leviticus 25:40.), return to their property and family (Leviticus 25:10, Leviticus 25:13), and release from the bitter labour of cultivating the land (Leviticus 25:11, Leviticus 25:12). This year of grace as proclaimed and began with the day of atonement of every seventh sabbatical year, to show that it was only with the full forgiveness of sins that the blessed liberty of the children of God could possibly commence. This grand year of grace was to return after seven times seven years; i.e., as is expressly stated in Leviticus 25:10, every fiftieth year was to be sanctified as a year of jubilee. By this regulation of the time, the view held by R. Jehuda, and the chronologists and antiquarians who have followed him, that every seventh sabbatical year, i.e., the 49th year, was to be kept as the year of jubilee, is proved to be at variance with the text, and the fiftieth year is shown to be the year of rest, in which the sabbatical idea attained its fullest realization, and reached its earthly temporal close.

And thou shalt number seven sabbaths of years unto thee, seven times seven years; and the space of the seven sabbaths of years shall be unto thee forty and nine years.

Le 25:8-23. The Jubilee.

8-11. thou shalt number seven sabbaths of years-This most extraordinary of all civil institutions, which received the name of "Jubilee" from a Hebrew word signifying a musical instrument, a horn or trumpet, began on the tenth day of the seventh month, or the great day of atonement, when, by order of the public authorities, the sound of trumpets proclaimed the beginning of the universal redemption. All prisoners and captives obtained their liberties, slaves were declared free, and debtors were absolved. The land, as on the sabbatic year, was neither sowed nor reaped, but allowed to enjoy with its inhabitants a sabbath of repose; and its natural produce was the common property of all. Moreover, every inheritance throughout the land of Judea was restored to its original owner.

25:8-22 The word jubilee signifies a peculiarly animated sound of the silver trumpets. This sound was to be made on the evening of the great day of atonement; for the proclamation of gospel liberty and salvation results from the sacrifice of the Redeemer. It was provided that the lands should not be sold away from their families. They could only be disposed of, as it were, by leases till the year of jubilee, and then returned to the owner or his heir. This tended to preserve their tribes and families distinct, till the coming of the Messiah. The liberty every man was born to, if sold or forfeited, should return at the year of jubilee. This was typical of redemption by Christ from the slavery of sin and Satan, and of being brought again to the liberty of the children of God. All bargains ought to be made by this rule, Ye shall not oppress one another, not take advantage of one another's ignorance or necessity, but thou shalt fear thy God. The fear of God reigning in the heart, would restrain from doing wrong to our neighbour in word or deed. Assurance was given that they should be great gainers, by observing these years of rest. If we are careful to do our duty, we may trust God with our comfort. This was a miracle for an encouragement to all neither sowed or reaped. This was a miracle for an encouragement to all God's people, in all ages, to trust him in the way of duty. There is nothing lost by faith and self-denial in obedience. Some asked, What shall we eat the seventh year? Thus many Christians anticipate evils, questioning what they shall do, and fearing to proceed in the way of duty. But we have no right to anticipate evils, so as to distress ourselves about them. To carnal minds we may appear to act absurdly, but the path of duty is ever the path of safety.
