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.

Jamieson-Fausset-Brown Bible Commentary

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.

Matthew Henry's Concise Commentary

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.
