BEFORE YOU TITHE, YOU NEED TO UNDERSTAND THE MEANING OF TITHING!

"And thou shalt truly tithe all the increase of thy seed, that the field bringeth forth year by year.
And thou shalt EAT BEFORE THE LORD thy God, in the place which He shall choose to place His name there, THE TITHE of thy corn, of thy wine, and of thine oil, and the firstlings of thy herds and of thy flocks; THAT THOU MAYEST LEARN TO FEAR THE LORD THY GOD ALWAYS...
At the end of three years thou shalt bring forth all the tithe of thine increase the same year, and shalt lay it up within thy gates: and the levite (because he hath no part nor inheritance with thee,) and the stranger, and the fatherless, and the widow, which are within thy gates, shall come, and shall eat and be satisfied; that the Lord thy God may bless thee in all the work of thine hand which thou doest." (Deuteronomy 14:22-29)

"And the priest the son of Aaron shall be with the Levites, when the Levites take tithes: and the Levites shall bring up THE TITHE OF THE TITHES UNTO THE HOUSE OF OUR GOD, to the chambers, into the treasure house." (Nehemiah 10:38)

The scriptures revealed three categories of tithes:
1. The yearly tithes
2. Three yearly tithes
3. The tithe of tithes

The yearly tithes is taken to the temple in Jerusalem by the tither. If Jerusalem is far from his house, he is to convert the tithes into money. When he gets to the temple in Jerusalem, the tither is not to give the money to anyone. In Jerusalem, the tither is commanded to use the tithe money to buy any food of his choice, which he takes to the temple. The tither then eats his tithe in God's presence and gives a portion from it to the Levites, the widow, the poor and the fatherless.

The three yearly tithes is gathered within the tithers own gate. The tither then invites the Levites, the widow and the fatherless to eat with him within his own gates.

The tithe of tithes is the 10% portion of the tithes from the yearly and three yearly tithes which is given to the Levites. It is the Levites who take the tithe of tithes from the portion they received from God's people to the storehouse in the temple- that's the priests portion.

"Will a man rob God? Yet ye have robbed me...in tithes and offering... Bring ye all the tithes into the storehouse, that there may be meat in mine house..." (Malachi 3:8-10)

The purpose of tithes is that believers may learn to fear the Lord and put God first in their life.

The people of Israel observed tithes by eating the yearly/three yearly tithes with the Levites and the poor as commanded by the Lord.
However, the Levites who were commanded to take 10% from their portion to the temple for the priests' upkeep were not doing so. Hence God was angry with the Levites and told them they have robbed Him in their tithes...

Taking tithes to God's house is not to take money to the Levites or priests in the temple, rather its to take food/produce of your labour to the temple and to eat it before the Lord and to give a portion of it to the Levites and the poor.
The tither always eat from the tithes and then distribute the rest to the Levites and the poor.
Its the Levites who give the tithe of tithes (10% of their own portion) to the temple storehouse, so that the priests who are the direct descendants of Aaron could have a share. That's the proper tithing as shown in the scriptures.

WE DON'T TITHE IN THE NEW COVENANT, BUT WE GIVE!
"And that He died for all, that they which live should not henceforth live unto themselves, but unto Him which died for them, and rose again." (2Corinth 5:15)

In the old testament, the Israelites could tithe because they had possessions. Hence, 10% is given to God as shown above and 90% is kept for themselves.

However in the new covenant we cannot tithe because all believers are priests under Christ the great High Priest. Priests don't give tithes!
As priests we are forbidden from having any possession or inheritance: God alone is our possession, portion and inheritance.

What this means is that we are possessors of nothing but stewards of everything that we have.
So we are to give freely, willingly, according to our own ability as God has prospered us...
