Did you know that the Bible speaks on gangs?
It really does, and I read it a long time ago so I had to look online to find where it was exactly. I thought it was Psalms 1, yet that couldn't be...I found it is Proverbs 1.
It never says "gang" exactly but it speaks on gang activities. "For their feet run to evil, and make haste to shed blood." It warns you to not join them when somebody asks you to. It tells you that, by their deeds, they really kill themselves.
