James Strong's index (19th century) assigns a stable number to each Hebrew and Aramaic lemma in the Old Testament and each Greek lemma in the New Testament—H#### for Hebrew and G#### for Greek—so you can connect the original word to brief lexical notes and see how the KJV (and related tradition) glossed it. It is a reference work for word study, not inspired text: entries are concise, sometimes dated, and tied to the King James tradition. Use them with Scripture in Read—especially when a commentary or study Bible cites a Strong's number—not as the last word on what a passage means.
