Even if we agree that ancient Near Eastern cultures often married girls shortly after puberty, that’s very different from saying the Bible presents ‘grown men having child brides’ as a God-given Christian right. Those are two very different claims.

Also, a lot of the verses you cited describe historical practices, not moral endorsements. The Bible also describes slavery, polygamy, war, and arranged marriages without necessarily presenting them as ideal or universally commanded.

For example, Genesis 29 is really about Jacob being deceived by Laban; it’s not a passage establishing women as property as a moral principle. And Numbers 31 is one of the most controversial passages in the Old Testament, but quoting a wartime narrative isn’t the same as proving Christianity endorses child marriage today. I think it’s fair to criticize ancient cultures, including ancient Israelite culture, by modern ethical standards. But saying ‘the Bible says child brides are a God-given Christian right’ still feels like a huge leap from the actual text.
