Our Scripture reading today is Leviticus 25:9-10.
Verse 10, "And proclaim liberty throughout all the land unto all the inhabitants thereof:"
What was the jubile?
This most extraordinary of all civil institutions, which received the name of "Jubilee" from a Hebrew word signifying a musical instrument, a horn or trumpet, began on the tenth day of the seventh month, or the great day of atonement, when, by order of the public authorities, the sound of trumpets proclaimed the beginning of the universal redemption. All prisoners and captives obtained their liberties, slaves were declared free, and debtors were absolved. The land, as on the sabbatic year, was neither sowed nor reaped, but allowed to enjoy with its inhabitants a sabbath of repose; and its natural produce was the common property of all. Moreover, every inheritance throughout the land of Judea was restored to its original owner. Jamiesson, Fausset and Brown
 
This celebration took place once every 50 years.  The trumpets were the "voices" that spread the news of the jubilee.  Today, the Lord Jesus has provided freedom for all mankind.  Praise the Lord!  It is our responsibility to proclaim the message of liberty that can be obtained freely by faith in His death, burial and resurrection.  Sin keeps people in bondage, but the Lord Jesus sets them free.  Rejoice today in the liberty you have in Him!
