And I looked, and, see, a Lamb stood on the mount Sion, and with him an hundred forty and four thousand…
The words cannot be literally understood, but must be taken in the sense of similar words of the Apostle Paul, when, writing to the Corinthians, he says, "For I am jealous over you with a godly jealousy; for I espoused you to one husband, that I might present you as a pure virgin to Christ." Such a "pure virgin" were the hundred and forty and four thousand now standing upon the Mount Zion. They had renounced all that unfaithfulness to God and to Divine truth which is so often spoken of in the Old Testament as spiritual fornication or adultery. They had renounced all sin. In the language of St. John in his first Epistle, they had "the true God, and eternal life." They had "guarded themselves from idols."
