She has forced all the nations to drink the wine of her passionate sexual immorality [Note: The word "passionate" here could also mean "angry"]."read more.
Then a third angel followed them. He said in a loud voice, "If anyone worships the beast and his statue, and receives a mark on his forehead or on his hand, he will also [have to] drink the wine of God's anger, as an undiluted mixture in the cup of His anger. And he will be tortured with burning sulphur in the presence of the holy angels and in the presence of the Lamb.

After this I saw four angels standing at the four corners of the earth. They were holding back the four winds of the earth so that no wind would blow on the earth, on the ocean or on any tree.

[Meanwhile] an angel [sent] from the Lord spoke to Philip and said, "Get up and travel south on the road from Jerusalem to Gaza; that is a deserted region." So, he went and [eventually] came across a man who was the Ethiopian Queen Candace's treasurer. He was a high official and was also a eunuch [Note: This was a man without normal sexual activity], who had been to Jerusalem to worship [i.e., probably as a Jewish proselyte]. He was returning [to his home in Ethiopia] and was sitting in his chariot [Note: Chariots were stopped on long journeys occasionally for resting, eating, reading, etc.] reading [a scroll of] the prophet Isaiah.read more.
The Holy Spirit said to Philip, "Go on up close to the chariot." So, Philip ran over to it and [when he got near enough] he heard the Ethiopian eunuch reading from Isaiah the prophet and asked him, "Do you understand what you are reading?" And the man replied, "How can I, except with someone's guidance?" Then he urged Philip to come and sit with him [in the chariot]. Now the passage of Scripture he was reading said [Isa. 53:7ff], "He was led out to be slaughtered as a sheep; He made no sound, just like a lamb when it was being sheared. He was subjected to [terrible] humiliation and deprived of justice. Who will [there be to] trace His descendants, since His life was taken from Him, [leaving no posterity]." The [Ethiopian] eunuch then asked Philip "Please tell me, is the prophet [Isaiah] writing about himself or about someone else?" So, Philip opened his mouth, and beginning [his message] from this Scripture [passage], he preached to him [about] Jesus. As they [i.e., Philip, the Ethiopian eunuch and his attendants] traveled along they came to a certain [body of] water. The [Ethiopian] eunuch said, "Look, here is [a body of] water, why can't I be immersed [right now]?" {{Verse is absent from many manuscripts}}. So, the eunuch ordered the chariot to be stopped; then both Philip and the [Ethiopian] eunuch went down into the water and Philip immersed the eunuch [into Christ]. And when they came up out of the water, the Holy Spirit of the Lord [supernaturally?] directed Philip to go elsewhere and the eunuch did not see him anymore, as he continued on his journey rejoicing.

I tell you that, in the same way, there will be more joy in heaven over one sinful person who repents [i.e., changes his heart and life], than over ninety-nine persons who do not need to repent.
