[Note: While I have addressed the Greek text and English translation in far greater detail among articles posted here: https://timothysparks.com/marriage, this article serves as a shorter explanation of the topic.]
Addressing the text of Matthew 19:9–To dismiss not over fornication is to dismiss not for fornication; thus, a non-fornication cause. Jesus does not address divorce for fornication (Mt. 19:9). It was the death penalty for such (Deut. 22:13-22; Lev. 20:10), not the divorce penalty.
