Leviticus 25:8 Meaning and Commentary

Leviticus 25:8

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.

Leviticus 25:8 In-Context

6 but those fruits shall be to you into meat, to thee, and to thy servant, and to thine handmaid, and to thine hired man, and to the comeling that is a pilgrim with thee; (but those fruits shall be food for you, yea, for thee, and for thy slave, and for thy slave-girl, and for thy hired man, and for the newcomer who is a foreigner, or a stranger, among thee;)

7 all things that come forth, shall give meat to thy work beasts, and [thy] small beasts. (all things that come forth, shall be food for thy work beasts, and thy small beasts.)

8 Also thou shalt number to thee seven weeks of years (And thou shalt count seven sabbaths of years to thee), that is, seven times seven, which (al)together make nine and forty years;

9 and thou shalt sound with a clarion in the seventh month, in the tenth day of the month, in the time of propitiation, that is, (in the time of) mercy, in all your land. (and thou shalt sound with a trumpet in the seventh month, on the tenth day of the month, that is, on the Day of Cleansing, or the Day of Atonement, in all your land.)

10 And thou shalt hallow the fiftieth year, and thou shalt call it remission, or forgiveness, to all the dwellers of thy land; for that year is [the] jubilee, that is, the joyful year; a man shall turn again to his possession, and each man shall go again to his first family, (And thou shalt hallow the fiftieth year, and thou shalt proclaim remission, or forgiveness, for all the inhabitants of thy land; for that is the Jubilee Year, that is, the Year of Restoration; a man shall return to his possession, and each man shall go back to his first family,)
