no I don't consider myself well versed in the old testament though I try to study it regularly. Much as I try to study all the scriptures we have.
I do know God gave us liberty and stewardship over what He has given us. As well as the wisdom to use it to take care of our needs and the needs of others.
I was reading through the Old Testament and came across a story that seemed very representative of our modern way of doing business. The story goes there was this guy, Ahab, king of Samaria, and he wanted this other guy's vineyard, Naboth's. So Ahad asks Naboth for it. Naboth says, "The LORD told me I can not give away the inheritance of my fathers." Ahab sulks and his wife sees him sulking. She helps out by getting Naboth stoned to death. Ahad then gets the vineyard he wanted. This seems like how we do business today. Some business guy wants something some politician or lawyer comes along and says, "Leave it all up to me. Just give me a little something you shall have what you want. No one will be the wiser." (Interesting sidenote: I was looking up the story since I forgot who the people's names were. The prophet the LORD sends word to about what happened is Elijah.)
