The Bible is the best-selling book of all time, and you can buy a copy in almost any bookstore. What's more, you'll find a copy in almost any public or academic library, in many law libraries and online. Online editions in English include the King James Bible and the Jewish Publication Society Bible.
To locate a word, quote, etc., search through the many versions of the Bible on the Bible Gateway. If that doesn't work, look in a quote book or check Strong's Exhaustive Concordance of the Bible. In most cases, quotes are drawn from the King James translation.
Note: You'll find Strong's in most large public libraries. I've ordered copies from NYPL Premium Services.
