Cross-referencing in Bible study refers to the practice of examining related passages and references within the Bible to gain a deeper understanding of a particular verse, passage, or topic. It involves comparing different parts of the Bible that address similar themes, ideas, or events to illuminate the meaning and context of the specific passage under study.

Proof-texting is a prevalent mistake in interpreting the Bible. This involves selectively using isolated Bible verses or passages to support a preconceived idea or argument without considering their original context, intended meaning, or the wider teachings of the Bible. It encompasses the act of extracting verses from their surrounding context and using them as "proof" to bolster a specific viewpoint.
