WHAT ABOUT PROVERBS 3:9?
Proverbs 3:9 (KJV) "Honour the LORD with thy substance, and with the firstfruits of all thine increase:"
The verse reads HONOUR the Lord with thy substance (wealth), not give to the Lord your wealth. The verse does not say honour the Lord with a tenth of your wealth, or give to the Lord a tenth of your wealth. This verse has nothing to do with tithing.
How does one honor the Lord with their wealth? By being a good steward of that wealth and use it to glorify the Lord the best one can.
The verse reads AND with the firstfruits of all thine increase. In other words, HONOUR the Lord with the firstfruits of all your produce, or crops (Hebrew word definition). Doesn't say give to the Lord the firstfruits of your produce, or crops.
For those who say that all thine increase can also mean all your income, read the next verse:
Proverbs 3:10 (KJV) "So shall thy barns be filled with plenty, and thy presses shall burst out with new wine."
Verse 10 makes it clear that increase in verse 9 is referring to the crops (produce) and not income.
