And I saw a strong angel proclaiming with a loud voice
This was not the uncreated angel, Jesus Christ; for he is after spoken of as the lion of the tribe of Judah, and as the Lamb in the midst of the throne, but a created one; though who he was, whether Gabriel, as some say, because his name signifies the strong or mighty One of God, is not material to be known; angels are said to be mighty, and to excel in strength: this is called so here, chiefly with respect to his voice, which he, by reason of his great strength, exerted so loudly, as to be heard by all the creatures in heaven, and in earth, and under the earth however, this was not John the Baptist, but if a minister of the Gospel, rather some one since, making the following proclamation:
who is worthy to open the book, and to loose the seals thereof?
suggesting, that if there was any such person, that he was desired to come, and do it; and it seems, that he must not only be one of power and ability, but of dignity and authority, a person of greatness and worth, from whence his ability arises; as he ought to be that can engage his heart to draw nigh to God, and take a book out of his right hand, this mysterious book of the Revelation, as it was indeed while sealed; and open and explain it to others, unseal it or exhibit it, as it afterwards was in the following scenes and visions, and gave a view of all that is contained in it; and not only so, but fulfil and accomplish all the prophecies in it; and who can, or is worthy to do all this, but he that sits at the right hand of God, and who is God as well as man? and this proclamation was made to stir up an earnest desire in John, and all the saints he represents, to know what was in this book; and to show the impotence of all creatures to make any discovery of it; and to illustrate, and set off with a greater foil, the glory, excellency, ability, and worth of Jesus Christ. There seems to be an allusion to the president of the temple calling to the priests under him, to attend to the several parts of service assigned them, saying unto them, (hkzv ym) , "whosoever is worthy, let him" do so and so F3.
