Leviticus 25:6-9

⁶Whatever the unworked land grows during the Sabbath year will be food for you. You, your male and female servants, your hired servants and the foreigners who live with you may gather food,

⁷and your livestock and also wild animals may eat whatever the land produces.

⁸You must count off seven Sabbaths of years, that is, seven times seven years, so that there will be seven Sabbaths of years, totaling forty-nine years.

⁹Then you must blow a loud trumpet everywhere on the tenth day of the seventh month. On the Day of Atonement you must blow a trumpet throughout all your land.
