How to use cross-references in your Bible reading

A cross-reference is a link from one verse to another that shares a word, a theme, a quotation, or an echo. The New Testament quotes the Old hundreds of times. Prophets echo one another across centuries. Paul weaves together passages from Genesis, Isaiah, and the Psalms in a single paragraph.

Reading those connections is one of the most rewarding ways to study Scripture, and Biblelexical makes it immediate.

How it works in the app

Tap any verse number in the reader and a panel opens showing related passages. The cross-references are drawn from the OpenBible.info dataset, which maps connections across the whole canon. Each reference includes the passage and a brief note on the connection: "quotation," "similar phrasing," "thematic parallel," and so on.

Tap a reference and the reader jumps to that verse. You can keep following the chain as deep as you like, then jump back to where you started.

Start with a familiar passage

Try opening John 1:1. The cross-references will show you Genesis 1:1 ("In the beginning"), 1 John 1:1 ("that which was from the beginning"), and Colossians 1:15-17 (Christ as the image of God and the agent of creation). Reading these together in one session gives you a picture of what John was doing, deliberately echoing Genesis to announce that something new had happened.

Follow quotations to their source

When Jesus quotes Deuteronomy in the wilderness, the cross-reference takes you straight to the original passage. You can read both side by side and see how Jesus applied the text differently than its original audience might have expected. The same works for every New Testament quotation of the Old: a direct line from the apostle or evangelist back to the prophet.

Notice the patterns

Some verses have dozens of cross-references. Others have only one or two. The density of connections can tell you something: a verse that the biblical authors returned to again and again is probably important. The cross-reference list becomes a kind of commentary written by Scripture itself, showing you which passages the biblical writers thought belonged together.
