These are the Greek words from John 10 that I'm speaking about:

Know: ginōskō; a prolonged form of a primary verb; to “know” (absolutely) in a great variety of applications and with many implications (as follow, with others not thus clearly expressed): — allow, be aware (of), feel, (have) know(-ledge), perceived, be resolved, can speak, be sure, understand.

Name: onoma; from a presumed derivative of the base of ginōskō; a “name” (literally or figuratively) (authority, character): — called, (+ sur-)name(-d).

Truly: amēn; of Hebrew origin; properly, firm, i.e. (figuratively) trustworthy; adverbially, surely (often as interjection, so be it): — amen, verily.
(The word "amen" is a most remarkable word. It was transliterated directly from the Hebrew into the Greek of the New Testament, then into Latin and into English and many other languages, so that it is practically a universal word. It has been called the best known word in human speech. The word is directly related -- in fact, almost identical -- to the Hebrew word for "believe" (amam), or faithful. Thus, it came to mean "sure" or "truly", an expression of absolute trust and confidence. -- HMM)

Thanks for listening, my friends!
