“This Hebrew word means firm, and hence also faithful (Revelation 3:14). In Isaiah 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 (Revelation 3:14).
It is found singly and sometimes doubly at the end of prayers (Psalm 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 (Numbers 5:22; Deuteronomy 27:15-26; Nehemiah 5:13; 8:6; 1 Chronicles 16:36). In the primitive churches it was common for the general audience to say “Amen” at the close of the prayer (1 Corinthians 14:16). The promises of God are Amen; i.e., they are all true and sure (2 Corinthians 1:20).”–Easton’s Bible Dictionary. ◊ Got Questions? ⇒”Why do we end our prayers with Amen?”
“One of the distinguishing names of the Lord Jesus Christ, as Christ God-man Mediator. For so Jesus condescended to make use of it. (Rev. iii. 14.) And the meaning of it, in the original language, shews the great blessedness of it, as it concerns His people, in the Lord Jesus condescending to do so. For the word, in the original Greek from whence it is taken, means verily, certain, sure, true, faithful. And surely, the Lord Jesus Christ is all these, and infinitely more, Jehovah’s Yea and Amen, as he saith Himself; the Amen, the faithful and true witness, the beginning of the creation of God; that is in His mediatorial character.
And it is worthy our closest remark, that our Lord very frequently began His discourses with this word, and repeated it—Verily, verily, I say unto you;” that is, in plain terms, (and indeed, it is the very word in the original) Amen, Amen. And it is yet worthy of further remark, that none but the Lord Jesus ever did use such words, at the opening of the discourse, by way of confirmation. As if the use of it was particularly His, and belonged to Him only, as His name. All the gospels, indeed, end with Amen. But then, this seems to be but as a further proof that they are His, and He puts, therefore, His name as a seal at the end of them, by way of establishing their truth.” Rev. Robert Hawker; DD., 1753–1827.
“So Be It”
“1. (interj., adv., & n.) An expression used at the end of prayers, and meaning, So be it. At the end of a creed, it is a solemn asseveration of belief. When it introduces a declaration, it is equivalent to truly, verily.
2. (v. t.) To say Amen (IS) to; to sanction fully.”
