{A strong angel} (aggelon ischuron). One needed ( 10:1  18:21 ) "whose call could reach to the farthest limits of the
universe" (Beckwith) and so "with a great voice" (en ph(936e)(8869)
megal(8869), in a great voice, as in  14:7,9,15 , and without en
 5:12  6:10  7:2,10  8:13  10:3 , etc.). See en ischur(8369) ph(936e)(8869)
( 18:2 ). {Proclaiming} (k(8872)ussonta). Present active predicate
participle of k(8872)uss(935c), to herald, to preach. {Worthy to open
and to loose} (axios anoixai kai lusai). Worthy by rank and
character (cf.  Joh 1:27 ) as well as by ability (edunato,
verse  3 ), followed by two infinitives (first aorist active) of
anoig(935c) and lu(935c), though hina and the subjunctive can be used
after axios as in  Joh 1:27 . Here axios is like hikanos
(capable, qualified) as in  Mt 8:8 . The articles here (	o,
tas) refer to the book and the seals in verse  1 . It is a
husteron-proteron, since the loosing of the seals precedes the
opening of the book.
