Which biblical book is named in the Liberty Bell’s inscription?

The Liberty Bell’s inscription quotes the biblical book 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 quotation comes from Leviticus 25:10, which concerns proclaiming liberty during the biblical Jubilee year.

The bell was cast in London in 1752 for the Pennsylvania State House, now Independence Hall. It cracked during an early test, was recast in Philadelphia, and was installed in the State House steeple. The familiar large crack developed during the early nineteenth century, and the bell has not been rung since 1846.

The Liberty Bell became a national symbol of independence and abolition. Its association with American independence grew especially strong after the Revolutionary era, although there is no evidence that it rang on July 4, 1776. The bell is now displayed in the Liberty Bell Center in Philadelphia.
