Chapter 24
Laws about divorce...
A woman divorced, who remarries, and then is divorced a second time or widowed, may not return to her first husband again. Deuteronomy calls this an abomination. That's what it calls homosexuality. This is the only law mentioned here. Nothing about what circumstances allow divorce. MSB note says that the abomination is that since she was sent away for other than adultery - because she'd have been stoned, not divorced, over adultery - that it was not accepted as an end to the marriage by God. In His eyes, when she remarried, the woman committed adultery, and so from the perspective of her first husband, she is now a adulteress, and they were not to be taken back. MSB note says divorce proliferates adultery.
The next section has several more laws reiterated, seemingly - at least to me - at random.
13 You shall restore to him the pledge as the sun sets, that he may sleep in his cloak and bless you. And it shall be righteousness for you before the LORD your God. [Deu 24:13 ESV]
If you loan a very poor man money, and the collateral is something he needs nightly, you must give it back each night, so he can use it, then take it from him again the next day. The point is not to take advantage of the poor. Loaning them money does not give you the right to be cruel to them.
The next verse expresses a similar principal:
14 "You shall not oppress a hired worker who is poor and needy, whether he is one of your brothers or one of the sojourners who are in your land within your towns. 15 You shall give him his wages on the same day, before the sun sets (for he is poor and counts on it), lest he cry against you to the LORD, and you be guilty of sin. [Deu 24:14-15 ESV]
16 "Fathers shall not be put to death because of their children, nor shall children be put to death because of their fathers. Each one shall be put to death for his own sin. [Deu 24:16 ESV]
I'm guessing that many cultures of that time practiced this sort of punishment. God's laws make each responsible only for his own sin. Evil is purged from the land by executing the guilty person, not the guilty person and his family. Evil is not genetic in the sense that willingness to commit the worst crimes is passed down. Sin itself - imperfection in our natures - is passed down. But each can resist. Or each can succumb.
Several laws about leaving some produce in the field for the hungry, the sojourner, and the widows and orphans. You weren't to strip your crops completely, but always leave some for those in need to come and gather for themselves. Hmm...It was to be left on the plants, in the field. There is no admonition to pick it, inspect it, box it, and deliver it to those who need it. They are required to come and help themselves.
