2. Ἄλλον, another) This other angel is distinguished either from the angel who makes proclamation, ch. 5:2; or from the four angels who hurt, in this passage. 13. Σφραγίσωμεν, we may seal) By this sealing, the servants of God out of the tribes of Israel are preserved, all along from the time of John, against the calamities which threaten under the seven trumpets. Before this there had been no need of sealing, before the danger. The ancestors are sealed at one time, and their posterity at another.
