I guarantee you that if after the sacrifice of the firstborn calf, that was the only calf the cow ever had, the farmer would certainly note that to anyone who cared.

So you agree that "first born" does not mean there must be a second born. Thanks for obliterating your own feeble argument.

I have two children. I refer to my daughter as my first born. If she were my only child, that’s what I would say, unless or until there were more children. This is getting stupid - I’m done.
