Deuteronomy 24, 25, & 26

If God hates divorce then why did He allow it in the law? How did these rules protect women from their former husbands? How seriously did God treat the crime of human trafficking? How were Israelites to handle taking loans from each other? Why was it important to pay someone immediately after they had done their job? Is there a contradiction in the law and the Bible in how the sins of the father shouldn't lead to the deaths of the sons? Why was God so adamant about protecting the sojourner, widow, and orphan in the land? How did God protect them in the law? Why did some judgments in court lead to men being whipped and how was this supposed to show mercy? Why was an ox not supposed to be muzzled while working? What was a brother supposed to do to his sister-in-law if her husband died? Was it evil for God to put into the law that the Amalekites were supposed to be wiped out? What is the importance of the firstfruits tithe? What is the creed the Israelites would use to speak about their history and why is it important? How important was it that they all agreed to do the things in the law when they said it all before God?
