🔼The name Ophir in the Bible
Ophir is one of many sons of Joktan, the brother of Peleg (Genesis 10:29), and Peleg became the ancestor of Abraham, while the Joktanites are the last mentioned Shemite generation before the tower of Babel was built.
Much later a typically auriferous land of Ophir is mentioned, which may or may not be the land that the descendants of the first Ophir settled (1 Kings 9:28, Psalm 45:9, Isaiah 13:12).
The name Ophir is mostly spelled אופיר, but in Genesis 10:29 it's אופר (Ophar) and in 1 Kings 10:11 it's אפיר (Aphir).
🔼Etymology and meaning of the name Ophir
The etymology and original meaning of the name Ophir are unclear. Fuerst's Hebrew & Chaldee lexicon to the Old Testament assumes that the name Ophir consists of two elements, and derives the first one from the root group אוה (awa I, II & III):
The second part of the name supposedly comes from an Arabic equivalent meaning riches. The name could thus mean Coast Of Riches or Mark Of Wealth. NOBSE Study Bible Name List simply reads Rich. Jones' Dictionary of Old Testament Proper Names reads Abundance.
However, whatever the original meaning of the name Ophir might have been, a Hebrew audience would have surely noted the distinct similarity between the name אופר and the root group אפר (apr I & II):
That means that the name Ophir would probably remind a Hebrew audience of either turbans or awninged chairs. And if it didn't, it surely would have reminded them of the name אפרים (Ephraim). That name is a bit of a mystery too, but it's commonly understood to mean Doubly Fruitful. For a nation known for its gold, that would be warranted to say the least.
