Matthew Poole and continuators on Revelation 6:1

1 AND I saw when the Lamb opened one of the seals , and I heard, as it were, the noise of thunder, one of the four beasts saying , Come and see .

Iohn's Vision continueth still; by the Lamb he means Christ, the Lamb oft mentioned, chap. 5. and by one of the Seals, one of the seven Seals mentioned chap. 5.1. that were set upon the Book which Iohn saw in the Right-hand of God the Father, given to Christ, v. 7. Christ began to discover the Counsels of God relating to that first Period of his Church.

And Iohn heard one of the four living Creatures speaking to him with a great and terrible Voice like the Noise of Thunder.

Inviting him to come near, or to attend and see.
