The biblical book quoted in the Liberty Bell’s inscription is Leviticus.
The bell bears the words “Proclaim LIBERTY Throughout all the Land unto all the Inhabitants Thereof,” followed by the reference “Leviticus XXV. V X.” The wording comes from Leviticus 25:10, a passage about proclaiming liberty and observing a jubilee year.
The Pennsylvania Provincial Assembly commissioned the bell in 1751, and it was cast in London in 1752. It was originally known as the State House Bell because it hung at the Pennsylvania State House, now Independence Hall. The name “Liberty Bell” became widely established much later, especially through abolitionist use in the nineteenth century.
Popular tradition says the bell rang when the Declaration was adopted on July 4, 1776. Historians consider it more likely that it rang during the public announcement on July 8, but no contemporary account proves that the bell itself was rung.
