There is no NT tithe precept but there is one concerning giving:
2 Corinthians 9
6 But this I say, He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully.
7 Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.
The OT tithe was for citizen landowners and their agricultural gain.
It was to be brought to the Israeli capitol Jerusalem. It was an income tax.
The OT tithe was to be paid in kind - 20 new sheep - 2 went to the Lord (and any firstborn males) brought to the temple or a levite in your neigborhood.
There were conditions which excused you from the OT tithe but then you had to redeem the tithe and use the money for a celebration and you were required to invite priest(s).
Laborers were not required to tithe.
We (NT believers) in fact own nothing, everything we have is from our father in heaven and is His anyway.
We are not under the law but under the guidance of the Holy Spirit.
Galatians 5:18 But if ye be led of the Spirit, ye are not under the law.
While the NT does not command tithing neither does it forbid it (as long as the 2 Corinthians precepts aren't ignored).
So look again at the passage in 2 Corinthians
2 Corinthians 9
6 But this I say, He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully.
7 Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.
There are other precepts for giving:
Faith - The just shall live by faith.
God's glory - 1 Corinthians 10:31 Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God.
When you give an account of the deeds done in the body it will be to God and not anyone here at the BB.
It is your decision.
