Leviticus 25:10–11

10 You are to consecrate the fiftieth year and proclaim freedom in the land for all its inhabitants. It will be your Jubilee,c when each of you is to return to his property and each of you to his clan. 11 The fiftieth year will be your Jubilee; you are not to sow, reap what grows by itself, or harvest its untended vines.
