Behold, he cometh with clouds. — Better, with the clouds. The reference to Christ’s words (Mark 14:62) is undoubted. In the “clouds” St. Augustine sees the emblem of the saints of the Church, which is His body, who spread as a vast fertilising cloud over the whole world.
Every eye shall see him, and they also which (they were who = “whosoever”) pierced him. — Here again is a reference to the incident of the piercing of Christ’s side (John 19:34), recorded only by St. John.
Shall wail because of him. — Or, shall wail over Him. The prophecy in Zechariah 12:10, is the suggesting one of this. But the passage in Zechariah describes the mourning of grief over the dead; the passage here is the mourning towards one who was dead, and is alive. He towards whom they now direct their sorrow is the One over whom they should have wailed when He was laid in His tomb.
