If you would like to give more I would be interested.
I'll cover stuff incrementally in several posts.
Tithe simply means "ten", or "tenth", which was holy to GOD:
And all the tithe of the land, [whether] of the seed of the land, [or] of the fruit of the tree, [is] the LORD'S: [it is] holy unto the LORD. Leviticus 27:30
The tithe was the tenth part, not 10%. If someone had 9 lambs born to them in a year, he was not required to give 10% of nine lambs for that year. The tenth lamb belonged to GOD.
Many religious leaders today define the tithe as being 10% of gross income, i.e., an income tax. The scriptures, though, paint a different picture. In the law, the tithe is always described as being the tenth of the increase from the field, i.e., crops and livestock. There were many income producing professions in ancient Israel, but there is no scriptural evidence that any of those who worked in them were ever required to pay tithes. It would have been contrary to the law of Moses for Jesus to have tithed on his wages he received as a carpenter, or for James, Peter, Andrew, and John to have tithed on the fish they caught in the Sea of Galilee. Income taxation is not a biblical concept; it is a modern invention.
The tithe honored GOD for giving the increase. A laborer works and is
owed wages, but a farmer works and is owed
nothing! Whatever he receives for his labors is a
gift of GOD. Men labored, but
GOD gave the increase. Making a tree produce fruit, or multiplying a seed 100-fold, is something no man can do, and glorifies GOD. The tithe, therefore, is returned to GOD to honor and glorify GOD the goodness of his giving. On the other hand, men labored and were
owed wages. Since there was no increase from GOD, no tithe was required. What they earned was theirs to keep - all of it. Whatever they decided to give of that was their choice and business, but it was not required by law.
This is all a picture of Christ. We labor in the flesh and are owed the wages of sin, which is death. The free gift of GOD, however, is eternal life in Christ through faith. We labor in Christ, but GOD gives the increase through his spirit.
