Leolaia,
Thanks for that explaination. Since the Jews were going into what was similar to a marriage contract, since they had to stay spiritual virgins in their worship to Jehovah, and the church today also must be clean spiritually (like virgins) then it would make sense that this is the "sign" that God would give them. Although they may have used circumcism prior to that for another purpose, it seems like if you believe God gave them this command, that he took something they were already familiar with - and gave it a new meaning by applying it to their relationship with God. This would be something they could readily relate too. Does this make sense?
As you said, there is not much information about this issue. But thanks for answering. Some may find a topic like this to be one to tear down someones faith but I feel the opposite. And NO I am not saying I think that was the purpose of the thread. It was obvious that it was a sincere question asked, and a very good one.
Lets face it, there is a lot of symbolism used in the bible and customs back then that would be foreign to us. And there is no black/white answer for everything. But, I really enjoyed this post because it got me to think outside the "normal box" we believers put ourselves in sometimes. And I learned something totally new which is that the nations surrounding Isreal also did the circumcism custom.
