“After these things I saw another angel coming down from heaven, having great authority, and the earth was illuminated with his glory. And he cried mightily with a loud voice, saying, ‘Babylon the great is fallen, is fallen, and has become a habitation of demons, a prison for every foul spirit, and a cage for every unclean and hated bird!’” Revelation 18:1-2.
“Listen! Behold, a sower went out to sow. And it happened, as he sowed, that some seed fell by the wayside; and the birds of the air came and devoured it. Some fell on stony ground, where it did not have much earth; and immediately it sprang up because it had no depth of earth. But when the sun was up it was scorched, and because it had no root it withered away.” Mark 4:3-6.
“Now as they heard these things, He [Jesus] spoke another parable, because He was near Jerusalem and because they thought the kingdom of God would appear immediately. Therefore He said: ‘A certain nobleman went into a far country to receive for himself a kingdom and to return. So he called ten of his servants, delivered to them ten minas, and said to them, “Do business till I come.” But his citizens hated him, and sent a delegation after him, saying, “We will not have this man to reign over us.” And so it was that when he returned, having received the kingdom, he then commanded these servants, to whom he had given the money, to be called to him, that he might know how much every man had gained by trading.’” Luke 19:11-15.
“Again, the kingdom of heaven is like a dragnet that was cast into the sea and gathered some of every kind, which, when it was full, they drew to shore; and they sat down and gathered the good into vessels, but threw the bad away.” Matthew 13:47-48.
