You kindly answered my question about Og, king of Bashan. However, I am not clear on how to understand your last comment, "...is a Midrash and should be understood as such." Please clarify.

The Midrash (Aggadah) is a way of expounding on the verses of Tanach. The Rambam (Maimonides) explains that the Midrash might not be meant to be understood literally as it has a deeper idea that is brought through a simple story or comment. Same in your case, it might have a message or a deeper meaning and not to be literally understood. (see also in the Disputation of Ramban 39)
