No tithe outside of Israel?

It's my understanding that according to the Law, the tithe was produce and live stock. If a farmer needed to redeem it for his family, he could tithe the monetary value of the produce and live stock, but, he had to pay a 5% penalty. Although I'm not clear on if it was 5% in addition to the tithe, or if was 5% of the tithe amount.

Either way, this is why some believe only tithing 10% of one's income in money violates the Law, if they profess to being lawkeepers.

Of course, many believe that under grace, one is to give as they have determined, kind of like a pledge or vow. Thus, if one determines to give 10%, they're perfectly fine.
