Leviticus 25:8

“And thou shalt number seven sabbaths of years unto thee, etc.] 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,…”

“THE JUBILEE. (Lev. 25:8-23) 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…”

“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. Leviticus 25:9 Cause the trumpet of the jubile to sound - Rather, cause the sound of the cornet to go through (the land). The word jubile does not occur in this verse in the Hebrew. The trumpet is the shofar שׁפר shôphār, i. e. the cornet (rendered “shawm” in the Prayer-Book…”

“25:8-17 The Year of Jubilee took place every fiftieth year as a release from obligations and servitude. The same year was also treated as a Sabbath year with no farming. Some scholars argue that the forty-ninth year served as both Sabbath (seventh) and jubilee (fiftieth) years. A simple count of fifty years would place the Year of Jubilee immediately after the seventh Sabbath year, which would mean two consecutive years without harvests. • Each Year of Jubilee the land was to revert to the clan or tribe that had originally received it under Joshua (Josh 13–21). Land had two functions: (1) It provided an economic basis for existence; and (2) it tied the landowner to his ancestors and, through…”

“Lev 23:15; Gen 2:2 Leviticus 25:9”

“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). Lev 25:8-9 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…”
