The rivers of Babylon flow, and fall, and carry away... Jesus is alone on earth, not merely with no one to feel and share His agony, but with no one even to know of it. Heaven and He are the only ones to know.
Jesus is in a garden, not of delight, like the first Adam, who there fell and took with him all mankind, but of agony, where He has saved Himself and all mankind
He suffers this anguish and abandonment in the horror of the night
Jesus will be in agony until the end of the world. There must be no resting in the meantime...
