Inside the basket was sitting a woman, personifying the final wicked system found in Revelation 17:3-5. The wicked system is represented as a basket with a woman held captive inside under a lead lid. Since storks are unclean birds (Leviticus 11:19; Deuteronomy 14:18) these must be agents of evil, demonic forces, protective of the wicked secularism, who set up the final system of evil. The destination of the women bearing the basket was Shinar. There it will be placed in a “house,” possibly referring to a temple, in which it would be set on a base or pedestal as an idol. The secular commercialism is central to the final world system. The vision is unmistakably looking forward to the final Babylon of Revelation 17, 18 at the second coming of Christ.
