Jubilee
The fiftieth year, reached after seven sabbatical cycles of seven years and announced by a ram’s-horn blast — the year when debts were released, the enslaved set free, and every family’s land returned to it. It runs on the same seven-times-seven-into-fifty structure as the Feast of Weeks, on a higher scale: the pattern of seven resolving into liberty and return. Synonyms: yobel, year of release, year of liberty. See also Sabbatical year.
