What are all of the instances in which Christ discusses marriage?

I am not entirely convinced that the idea of marriages being divinely blessed or preferable of a Christian life is entirely Christian. It seems, aside from Matthew 19, that Christ is entirely unconcerned with the concept of marriage and teaches that a chaste life is the ideal Christian life. Most of the sentiment around marriage in Christian life seems to come from Pauline writings. Are there any other examples of Christ discussing the topic of erotic love/marriage aside from this discussion around divorce/eunuchs?
