I said somethiing useful in message #21, about an Old Testament ritual called "Redemption of the first born", which - despite its title - does not imply the existence of a second-born. But this was ignored completely.
Well, there are a couple of problems.
You don't quote anyone you're responding to, so it's difficult to figure out who you're talking to, or what you're talking about.
Secondly, the rendering of Matt. 1:25 is determined by the Greek textual evidence of the verse, not about a reading in the Torah. So your post was probably ignored because it was deemed irrelevant.
