Babylon in one word describes all of Paul's Kingdom because it has many voices of many ministries all selling something besides Jesus' perfect ministry the Gospel. This includes all Catholics, Protestants, and Catholic Abominations such as Islam and Communism. These verses command Jesus' people to leave Paul's kingdom of prostittuion and corruption.
One big identifier marking these groups is elders which Jesus did not add to his church, but Paul added to his denominations - practically all denominations no matter what their brand name are ruled by elders which based on the origin of elders in Egypt, the land of unsaved, ungodly slave drivers relative to God's people Israel, which tells us eldership is a position of spiritual death giving Satan slave driving control over God's spiritual people. That is why Paul's Christianity is so bad that it cannot be redeemed but must be come out of.
The man child will obey this verse earlier before they ascend. There are some interesting things for pioneers who obey. One can be likened to scales falling from their eyes so they like whatever they see more, instead of being focussed only on their denomination's teachings and whore spirit. That allows one to see clearly in following Jesus directly, which can bring many spiritual blessings, including direct help from Jesus our Creator instead of vicarious help from Paul's minions who are modern Pharisees.
It may be difficult at first for those who are the first to pursue Jesus only with no other people to fellowship with. But learning to fast from social life and primarily pray is very much worthwhile. When people come sent by God it is a spiritual blessing instead of just a soulish social event. When more people choose to pursue Jesus' Christianity instead of Paul's, everyone will need to remember the lessons of pursuing Jesus by prayer instead of backsliding into Paul's Pharisee social life and calling that church.
