What does Shiloh mean?
Etymology unsettled. Most often read 'tranquil, peaceful, place of rest,' linked to the sanctuary town Shiloh and a root sh-l-h. The cryptic term in Genesis 49:10 is alternatively read shelo, 'he whose it is' (taken messianically). The popular gloss 'his gift' is not well supported. Hedge as disputed; used for both sexes in modern practice.
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.
