Using Strong's Concordance to trace a Greek New Testament word back to its Hebrew root (via the Septuagint) provides deeper theological context. A prime example is the word "Lord" in
Romans 10:13, where the Greek Kyrios (G2962) refers back to the Hebrew Yahweh (H3068), transforming a general title into a direct, covenantal declaration of Jesus’s divinity.
Example: "Calling on the Name of the LORD" (
Romans 10:13)
Scripture: "For whosoever shall call upon the name of the Lord shall be saved" (
Romans 10:13, KJV).
The Greek Word: The word "Lord" is Kyrios (G2962), which means master, owner, or lord. In a Roman context, this could simply mean a polite address or a reference to Caesar.
The Hebrew Root: Paul is quoting
Joel 2:32. In the Hebrew text of Joel, the word is Yahweh (H3068), the personal, covenantal name of God (often translated as LORD in all caps in the Old Testament).
Depth of Understanding:
By looking up the Hebrew root through the Septuagint (the Greek translation of the Old Testament that the NT writers frequently used), we discover that Kyrios in this passage is not just a title of respect, but a specific replacement for the divine name of God.
Conclusion: Paul is explicitly equating Jesus with Yahweh of the Old Testament. Calling on the name of the Kyrios is not just a request for help; it is an act of worship acknowledging Jesus as the covenant-keeping God of Israel.
How to find this:
Look up "Lord" in
Romans 10:13 in a Strong’s Exhaustive Concordance.
Find the number G2962 (Kyrios).
Look at the cross-references in the Blue Letter Bible or Bible Hub for that verse, which will show it quotes
Joel 2:32, where the underlying word is H3068 (Yahweh).
Other excellent examples include studying "grace" (charis) by looking at the Hebrew chen (favor/grace) or "peace" (eirene) by looking at Shalom (wholeness/completeness).
