What are cross-references in the Bible?
Quick answer
Cross-references are notes (often in the margin or footnotes of a Bible) pointing to other verses that quote, allude to, or illuminate the passage you’re reading. They are an easy way to let Scripture interpret Scripture.
When the NT quotes the OT, cross-references show the source. When a passage echoes another, they let you trace the thread.
Many Bibles include cross-reference systems (Thomson’s, Treasury of Scripture Knowledge, etc.). Most digital Bibles make them one click away.
Practical use: when a verse puzzles you, follow the cross-references. Other passages often clarify what one verse alone leaves vague.
