And thou shalt number seven sabbaths of years unto thee, seven times seven years; and there shall be unto thee the days of seven sabbaths of years, even forty and nine years.
Targum Jonathan on Leviticus
And thou shalt number to thee seven Sabbaths of years, seven times seven years, and they shall be to thee the sum of the days of seven Sabbaths (or remissions, shemittin) of years, forty and nine years.
