Even the Law of Moses made some concessions to the hardness of people's hearts. The Pharisees tried to lure Jesus into the swamp of discussing divorce and when it might be permissible, according to Moses. Jesus refused to get drawn into their fruitless legal argument. Instead, he called them back to the beginning, before the law was given, before sin entered the world. God created us male and female, and he gave men and women to each other in marriage. Only within this framework of our created nature can human relationships flourish.
