The second beast - That which had the face of an ox.
And when he had opened the second seal - So as to disclose another portion of the volume. See the notes at Revelation 5:1.
I heard the second beast say - The second beast was like a calf or an ox. See the notes at Revelation 4:7. It cannot be supposed that there is any special significancy in the fact that the second beast addressed the seer on the opening of the second seal, or that, so far as the symbol was concerned, there was any reason why this living. creature should approach on the opening of this seal rather than on either of the others. All that seems to be designed is, that as the living creatures are intended to be emblems of the providential government of God, it was proper to represent that government as concerned in the opening of each of these four seals, indicating important events among the nations.
Come and see - See the notes on Revelation 6:1.
Perhaps the first noticeable feature in these symbols is the contrast in the color of the horses. This is doubtless designed to be significant. If the whiteness of the first horse denoted the purity of the gospel in the period which that symbol covers, the redness of the second horse would signify that in this period that original purity began to be corrupted. The mystery of iniquity already worked in Paul’s day; and the professed church of Christ, it would seem, was now so far corrupted by it as to require this change in the color of the symbol. Errors began to arise. Worldliness came in. The ecclesiastical power sought the alliance of the secular. Troubles and commotions were the result. The spirit of this period perhaps reached its climax as we come down to the days of Constantine, the first so-called Christian emperor, whose conversion to Christianity is dated by Mosheim in A. D. 323. — Ecclesiastical Commentaries.DAR 404.2
Of this period, Dr. Rice remarks: “It represents a secular period, or union of church and state. Constantine aided the clergy, and put them under obligations to him. He legislated for the church, called the Council of Nicaea, and was most prominent in that Council. Constantine, not the gospel, had the glory of tearing down the heathen temples. The state had the glory instead of the church. Constantine made decrees against some errors, and was praised, and suffered to go on and introduce many other errors, and oppose some important truths. Controversies arose; and when a new emperor took the throne, there was a rush of the clergy to get him on the side of their peculiar tenets. Mosheim says of this period, ‘There was continual war and trouble.’”DAR 404.3
This state of things answers well to the declaration of the prophet that power was given to him that sat on the horse “to take peace from the earth, and that they should kill one another: and there was given unto him a great sword.” The Christianity of that time had mounted the throne, and bore the emblem of the civil power.DAR 404.4
