Leviticus 25:8

And thou shalt reckon to thyself seven sabbaths of years, seven times seven years; and they shall be to thee seven weeks of years, nine and forty years.

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.

“‘You shall count off seven Sabbaths of years, seven times seven years; and there shall be to you the days of seven Sabbaths of years, even forty-nine years.
