The IAU catalogue's account
Originally from the Arabic word al-yad, "the hand," used in the Arabic Almagest in describing these stars. yed was applied as a star name to δ Oph in medieval times. Then in recent times, this application was extended to include both δ and ε, with the addition of the Latin distinctions for "foremost" and "hindmost," respectively.
