After searching and screening scriptures carefully, I found out that teaching and observing monetary tithing is a transgression of the tithing law biblically.
ARE YOU SURE?
1 John 3:4-5,9
 Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.  And ye know that he was manifested to take away our sins; and in him is no sin. …  Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
Because if one is attempting to obey the Law instead of believe God is indebted to observe the entire Law…and will be judged by the Law.
Clearly no one is justified before God by the law, because, “The righteous will live by faith.” The law is not based on faith; on the contrary, “The man who does these things will live by them.”
WHAT DOES TITHING LAW SAYS?
30 And qall 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 to the Lord. 31 rIf a man wants at all to redeem any of his tithes, he shall add one-fifth to it. 32 And concerning the tithe of the herd or the flock, of whatever spasses under the rod, the tenth one shall be holy to the Lord. 33 He shall not inquire whether it is good or bad, tnor shall he exchange it; and if he exchanges it at all, then both it and the one exchanged for it shall be holy; it shall not be redeemed.’ ”
The last verse is the most important part of this scripture for it highlights the context of the law.
A lot of Christian have been mislead on this subject….
You can leave a question for more scriptures about tithes.
