The Jubilee year described in Leviticus 25 is to be proclaimed every fiftieth year. America's Liberty Bell is inscribed with a translation of this passage's exhortation to "Proclaim liberty (deror) throughout all the land, and to all the inhabitants thereof." Rather than signifying general political liberty, the idea was more akin to freeing bondservants from debt-servitude. It meant the liberty to rejoin their natural families rather than having to remain in their creditor's household. Israelite families who had lost their land as a result of economic hardship were to be assured new plots in their traditional ancestral lands so as to provide them with the means of self-support.
