Leviticus 25:9-12

⁹And thou shalt make the sound of the trumpet to pass forth, in the seventh month on the tenth of the month, on the day of the expiations shall you make (the sound of) the trumpet to pass through all your land.

¹⁰And you shall sanctify the year of the fifty years, and proclaim liberty in all the land to all its inhabitants; it is and it shall be a jubilee to you; and each man shall return to his inheritance, and each to his family shall return.

¹¹A jubilee shall that year of fifty years be to you. Ye shall not sow nor reap the after crop, nor make vintage of the remainder,

¹²for it is a jubilee; it shall be sacred to you; of the growth of the field you may eat.
