Thank you for your perspective.This is not about a father giving away his daughter in marriage - it is about a betrothed husband and wife. In modern terms, it is saying that if a man and woman are engaged to be married - but, he "cannot wait" until the two of them are married - that he should "go ahead" with "answering" his "need" - and, they should "go ahead" and get married.
I read the passage again with that in mind because sometimes I change my mind since I am always learning. I very rarely consult commentaries but decided to here to get another opinion. For what it's worth, every one of the commentaries agreed with my explanation. I didn't cherry pick. There was a list on my KJ E-Bible site.
That doesn't matter as far as my main point. My reason for mentioning this passage is because it describes the age of marriage. Two reasons why I thought it relevant was because of original poster's question.
A. Age has no biblical relevance as long as they are adults and is not an issue with God. (Rainbow flag "churches" care less what God says so I will not even go there now.
It is a cultural thing and everyone has an opinion. Very few search the Scriptures to see what the Lord Who instituted marriage says about the matter.
I only read the original post an title before speaking. I doubtless offended someone and perhaps others since I did not regard their comments. That was not my desire, but I am frank and honest. One of many benefits of a mature POV is that you see beyond the public examples of failed marriages and weak preachers. IMHO, that's what is so creepy to me: marriages that are disposable like aluminum cans and pastors that build families on such teaching. I'm not looking down on any individuals, but come on folks there's a problem and it sure ain't the age gaps in this country!
B. I made the point of adulthood because one of the world's largest religions has a very sad custom of following their prophet Mohammad. He married, in the sense you described, Isha a six year old and consummated that at 9 years old.
The Bible describes marriage between one man and one woman. Today that institution is desecrated with divorce&remarriage examples over and over and over and over again by popular mega church pastors. Of course the typical member of such churches justify that for their own as I just witnessed once again in a couple with the 70(?) year old husband initiating a divorce with his young pretty wife. From the way they talked on their podcast, I thought they were close. A month ago she made the comment out of the blue how she liked his [awesome] body right in front of the live stream.
He wasn't showing anything outside of weapons.
Nothing indecent, he was discussing guns, ammo and hunting. She was helping. Now they are getting a divorce! Tragic.
At least they got a clear gospel witness the other day. If they both get/got saved, perhaps they will reconcile.
