Index of Commentary
Clicking on a section number, i.e. 134f, will take you to page 134, then locate the letter "f" along the left margin of the page.
The index is a cross-reference instrument designed to perform the opposite function of the glossary:
instead of looking up topics to study verses, you look up verses to study topics.
The index is where Bible commentary is also stored.
