The Treasury of Scripture Knowledge was, and still is, a Bible reference work first published around 1830, created by the London publisher Samuel Bagster (1772-1851). It is a set of cross-references. That is, it consists entirely of a book-length listing of cross-references, showing only the chapter and verse citations with no accompanying text. About the size of a complete Bible, the TSK is also organized like a Bible, beginning at Genesis and ending at Revelation. Each verse of the Bible is cross-referenced to several others to enable the reader to gain a true sense of each word and phrase as it is used in the Bible.
- 800,000 cross-references, listing verses that illustrate how words and phrases are used elsewhere in the Bible.
- Helps the reader interpret Scripture with Scripture.
- Brief chapter summaries.
- Dates and other notes.
The original Treasury of Scripture Knowledge is one of the most valuable Bible reference works ever to be published. Unlike a typical commentary, the TSK consists primarily of scripture references with very little "comment." Of course, there are "illustrative notes" (as so described by the original publisher), which include book summaries, chapter outlines, short explanations, and alternate readings often found in the margins of the Authorized Bible. However, the TSK remains unique in that its primary purpose is to present the reader with copious cross-references so that the Bible student may allow Scripture to be illuminated by the whitest of lights: Scripture itself.
