Where in the Bible Were Tithes Abolished when Jesus Established the New Covenant?
The covenant which prescribed them was abolished per Heb 8:8-13; Gal 4:21-26' 2 Cor 3:6-10.
Hey 8:8-13: For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah: 9 not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they continued not in my covenant, and I regarded them not, saith the Lord. 10 For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people: 11 and they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest. 12 For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more. 13 In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.
Galatians 4:21-26 Tell me, ye that desire to be under the law, do ye not hear the law? 22 For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman. 23 But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise. 24 Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar. 25 For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children. 26 But Jerusalem which is above is free, which is the mother of us all.
2 Corinthians 3:6-10 who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life. 7 But if the ministration of death, written and engraven in stones, was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away: 8 how shall not the ministration of the spirit be rather glorious? 9 For if the ministration of condemnation be glory, much more doth the ministration of righteousness exceed in glory. 10 For even that which was made glorious had no glory in this respect, by reason of the glory that excelleth.
The "commandment" for Levites and priests to collect tithes was "annulled" per Hebrews 7:5, 12, 18.
Hebrews 7:5-18 And verily they that are of the sons of Levi, who receive the office of the priesthood, have a commandment to take tithes of the people according to the law, that is, of their brethren, though they come out of the loins of Abraham: 6 but he whose descent is not counted from them received tithes of Abraham, and blessed him that had the promises. 7 And without all contradiction the less is blessed of the better. 8 And here men that die receive tithes; but there he receiveth them, of whom it is witnessed that he liveth. 9 And as I may so say, Levi also, who receiveth tithes, payed tithes in Abraham. 10 For he was yet in the loins of his father, when Melchisedec met him.
11 If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron? 12 For the priesthood being changed, there is made of necessity a change also of the law. 13 For he of whom these things are spoken pertaineth to another tribe, of which no man gave attendance at the altar. 14 For it is evident that our Lord sprang out of Juda; of which tribe Moses spake nothing concerning priesthood.
15 And it is yet far more evident: for that after the similitude of Melchisedec there ariseth another priest, 16 who is made, not after the law of a carnal commandment, but after the power of an endless life. 17 For he testifieth, Thou art a priest for ever after the order of Melchisedec. 18 For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof.
Jesus blotted out the handwriting of ordinances, per Col 2:14. Tithing was an ordinance per Num 18.
Colossians 2:13-15: And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses; 14 blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross; 15 and having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
The Temple which tithes supported was abolished in AD 70. God's temple is now within each believer per 1 Cor 3:16; 6:19-20.
1 Corinthians 3:16-17. Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? 17 If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.
1 Corinthians 6:19-20 What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? 20 For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s.
The priesthood which was supported by tithes was abolished in AD 70. God's priesthood is now within every believer per 1st Peter 2:9-10.
1 Peter 2:9-10 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light: 10 which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy.
The blessings and curses of tithing as part of the whole law have been abolished per Galatians 3:10-14.
Galatians 3:10-14 For as many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them. 11 But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith. 12 And the law is not of faith: but, The man that doeth them shall live in them. 13 Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree: 14 that the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith.
So what does this mean now that the commandment to give 10% has been abolished? Should you give nothing? Should you still give 10% or 20?
According to what is written in the scriptures, God looks at the heart and leaves the decision up to you. There is no longer a requirement to fulfill a specific number or quantity as it was under the Old Covenant. It is all left to the heart of the believer to decide what they want to do with their money and where and how they will give it.
2 Corinthians 9:6-7 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.
May God bless you in your walk with Him, and be wary of false prophets and malicious pastors who seek to rob you of the money you have earned and the money with which God has blessed you. Your money does not need to be funneled into churchianity programs or to support the unbiblical pastor/deacon salary heresy. Give in your community and support fellow Christians in need.
