Leviticus 25:8
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.
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.
