Revelation 10:2

And he had in his hand a little book open
By which is meant not the Bible, the Scriptures of the Old and New Testament; or the book of the Gospel, the substance of which lies in a little room, and is no other than the preaching of Christ, and him crucified, as God's way of salvation; and which is now more open and manifest, and more clearly made known unto the sons of men, under the Gospel dispensation, than it was before, and especially since the time of the Reformation, to which this book, and the prophecies of it, may have respect; but the same book is here designed, which in ( Revelation 5:1 ) is represented as in the right hand of him that sat on the throne, as shut and sealed; but the lion of the tribe of Judah, the Lamb in the midst of the throne, having taken it out of his hand, unloosed its seals, and opened it; and whereas we never read of his laying this book down, or of his delivering it to any other, he may be well supposed to be this mighty angel, who held it open in his hand: it may be said to be "a little book", because now not only many of the scenes and visions in it were exhibited, upon the opening of the seals; but because, at the time this vision refers to, many of its prophecies were accomplished, so that the bulk of it was greatly reduced; and it may be represented as "open", because the seals of it were unloosed, and the things in it revealed; and it is to be observed, that as the several seals of this book, and the opening of them, refer to the state of the empire, both as Pagan and as Christian, as has been seen; so the little book itself, clear of these seals, sets forth the state and condition of the church in the empire, under its different revolutions and appearances:

and he set his right foot upon the sea, and [his] left [foot] on the
earth;
which signifies that he was Lord and possessor of both, of the whole terraqueous globe, being the Maker and supporter of it; and that his Gospel should be spread all over the world, both on the continent and in the islands of the sea; and that his kingdom should be from sea to sea, and from the rivers to the ends of the earth; that the abundance of the sea should be converted to him, or the maritime parts of the world should be subject to the sceptre of his grace and government; and that the earth, and the uttermost parts of it, should be his possession, though it was now almost wholly in the hands of the Turk and pope; and it may be observed, that he set his foot upon both earth and sea, out of which the two beasts arise, ( Revelation 13:1 Revelation 13:11 ) , which shall be destroyed by him.
