G4246–πρεσβύτης–presbutēs

And Zacharias said to the angel, How may I be certain of this? For I am an old man, and my wife is far on in years.

πρεσβύτης, presbutēs “an old man,”

That old men are to be simple in their tastes, serious, wise, true in faith, in love, and of a quiet mind.

Πρεσβύτας Presbutas “[The] aged [men]”

πρεσβύτης presbutēs “aged”
