Not the last word, but the only reliable word.
This Hebrew word means firm, and hence also faithful Rev 3:14 In Isa 65:16 the Authorized Version has "the God of truth,
"which in Hebrew is "the God of Amen." It is frequently used by our Saviour to give emphasis to his words, where it is
translated "verily." Sometimes, only, however, in John's Gospel, it is repeated, "Verily, verily."
It is used as an epithet of the Lord Jesus Christ Re 3:14 It is found singly and sometimes doubly at the end of prayers
Ps 41:13 72:19 89:52 to confirm the words and invoke the fulfilment of them. It is used in token of being bound by an oath
Num 5:22 De 27:15-26 Ne 5:13 8:6 1Ch 16:36 In the primitive churches it was common for the general audience to say "Amen"
at the close of the prayer.
AV-verily 101, amen 51; 152
1a) metaph. faithful
2) verily, amen
2a) at the beginning of a discourse-surely, truly, of a truth
2b) at the end-so it is, so be it, may it be fulfilled. It was a custom,
which passed over from the synagogues to the Christian assemblies,
that when he who had read or discoursed, had offered up solemn prayer to God,
the others responded Amen, and thus made the substance of
what was uttered their own.
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)
