There is no embarrassment required for what I shared. You had indicated that the word marriage does not exist in the bible nor is it a biblical concept. That is factually untrue and I presumed that you had not seen these verses so I shared them. You did not say that where the bible mentioned marriage, the translators got it wrong.
The word "marriage" is an english word and therefore it will only be in translated versions of the bible. That does not mean that the word/concept of marriage is not in the bible. You chose to use an english word in your claim that it did not exist in the bible. I presumed you meant an english translation.
And I happily argue that the translators did not get it wrong. Your attempts to make a marriage all about sex confuses the issue. For example, when the bible speaks about marriage in Exodus 21:10, it is speaking about conjugal rights. Not simply sex but the right to sex based on their marital status.
Btw, even if I were wrong about something, why would I be embarrassed? People get things wrong all the time and I realize that I also get things wrong. I am not claiming perfection so there is no pedestal under me that you are knocking me off of.
