Many of these rules are beautiful.
We’ve got equality, fairness, compassion, social welfare, kindness to the disabled, anti-discrimination rules, generally against hate and superstition.
This was radical. We were reminded in the last chapter of the deity Moloch for whom children were apparently sacrificed, this God is not like that. Similarly, it might seem obvious in this chapter to tell parents not to make their daughters prostitutes, but that refers to temple practises of the local religions and was seen as a religious thing to do. These rules are dramatically different.
Its a picture of a really great society. Jesus blessed and adopted all this stuff for us when he quoted this chapter and said loving your neighbour one of the two greatest commandments, along with loving god. Love love love, love is all you need. And he told a parable to extend the Israelite concept of neighbour to anyone.
The latter half of the chapter is about not mixing in with the culture, fashion and practices of canaan where they will be settling. This section has the often quoted example of a dumb Leviticus rule, the one about not wearing a shirt with two types of fabric. Those rules seem a lot more arbitrary to us now. Though the gist of not being a slave to fashion, or taking your cues entirely from the society around you is still relevant to christians.
