And it puts under compulsion all persons, the small and the great, and the rich and the poor, and the free and the slaves, that they should give these a mark in their right hand or upon their forehead, 17 and that nobody might be able to buy or sell except a person having the mark, the name of the wild beast or the number of its name. 18 Here is where wisdom comes in: Let the one that has intelligence calculate the number of the wild beast, for it is a man’s number; and its number is six hundred and sixty-six.
In these few verses alone, they talk about a mark on the right hand and forehead, as well as not being able to buy or sell without that mark, and finally the number of the wild beast 666.
After studying the Revelation Climax book a couple of times with the JW's, I still don't recall a clear explanation for these verses above.
If we are so close to the end, wouldn't they know what 666 means by now?
