What does Jordan mean?
From the River Jordan, Hebrew Yarden, derived from the root y-r-d 'to go down, descend, flow down' - describing the river's descent. Long used as a given name, originally for those baptised in or with water from the Jordan.
What does Ophir mean?
Biblical place name (אוֹפִיר) for a region famed as a source of fine gold; popularly glossed 'gold' as a given name. Flagged: the Hebrew root itself is of uncertain derivation, so 'gold' derives from the place's reputation for gold rather than a literal word for the metal — it is a place name / 'gold-rich' byname.
