Scriptures like this I wondered about when I was in. A group of thieves who are conspiring to murder a man
and take his posessions and get all sorts of loot? That didn't seem realistic at all that this would be such a common occurence
that Solomon makes this specific warning but now it makes sense. If some people decide they want to ruin the reputation of someone else they pretty much do the same thing as this scripture. They 'find and innocent soul' who is an easy target. They 'swallow them alive' in slander. They go after their 'valuable things' which is their credit and reputation and seek to 'fill their houses with loot'. By doing this they look good and the other looks bad without doing any work. And sometimes this results in real death such as suicide. Proverbs 1 : 8-14.
