inward connection with the sabbatical year is indicated by the fact that the time for observing it was regulated by the sabbatical years (Lev 25:8).
The law for the Year of Jubilee refers first of all to its observance (Lev 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).
verses 8-9
Keeping the year of jubilee. Lev 25:8, Lev 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 Lev 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 (Exo 19:13, Exo 19:16, Exo 19:19; Exo 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” (Lev 25:10), - deliverance from bondage (Lev 25:40.), return to their property and family (Lev 25:10, Lev 25:13), and release from the bitter labour of cultivating the land (Lev 25:11, Lev 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 Lev 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
