Ver. 27,28. Matthew seemeth to expound this, Matthew 24:31; so doth Mark 13:27. Both speak to the same sense: And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from, one end of heaven to the other. This is certainly to be understood of the day of judgment, when the saints shall be glorified as the sons of God by adoption, and obtain the redemption of the body, Romans 8:23.
