I have read the Bible most of my life, but have never really studied it too much per se. After reading the divorce thread, I started wondering about all those leaders and kings like David and Solomon etc in the Old Testament who had multiple wives. What changed in a couple of thousand years into the New Testament where the leaders of the Christian Home Churches insisted that their leaders be married to only one wife? Did Jesus actually say marriage was now different, or, was this just something that the men in those churches made up as new rules? And, another question within the question that puzzles me is does this make David, Solomon and the many others in the Old testament sinners because of having multiple wives? Thanks you in advance for any wisdom you can impart to these perhaps basic (but for me pretty confusing) questions.
