Leviticus 25:11

25:11 That fiftieth year will be your jubilee; you must not sow the land, harvest its aftergrowth, or pick the grapes of its unpruned vines.

Leviticus 25:10

25:10 So you must consecrate the fiftieth year, and you must proclaim a release in the land for all its inhabitants. That year will be your jubilee; each one of you must return to his property and each one of you must return to his clan.
