OK, sorry for my ignorance, then looking closer to it it may be just that one word is falsely typed, and it should be "serva me" instead of "serva ma"
Let's ask our expert in Latin.
What do you think, Efy? Now after RC told it was definitely not Serbian, wouldn't it be possible "serva me, servabo te" to be a kind of marital oath, or smthng like that?
