Deuteronomy 14:22-29 (The Message)
22-26 Make an offering of ten percent, a tithe, of all the produce which grows in your fields year after year. Bring this into the Presence of God, your God, at the place he designates for worship and there eat the tithe from your grain, wine, and oil and the firstborn from your herds and flocks. In this way you will learn to live in deep reverence before God, your God, as long as you live. But if the place God, your God, designates for worship is too far away and you can't carry your tithe that far, God, your God, will still bless you: exchange your tithe for money and take the money to the place God, your God, has chosen to be worshiped. Use the money to buy anything you want: cattle, sheep, wine, or beer—anything that looks good to you. You and your family can then feast in the Presence of God, your God, and have a good time.
27 Meanwhile, don't forget to take good care of the Levites who live in your towns; they won't get any property or inheritance of their own as you will. 28-29 At the end of every third year, gather the tithe from all your produce of that year and put it aside in storage. Keep it in reserve for the Levite who won't get any property or inheritance as you will, and for the foreigner, the orphan, and the widow who live in your neighborhood. That way they'll have plenty to eat and God, your God, will bless you in all your work.
Is 'tithing' rewritten in the New Covenant? For this is given in the 'law' of the 'Old' and we are of Grace and no longer under the 'Law of the Letter'.
JESUS raised the standards of 'righteousness' through HIS teachings that 'exceeds' the righteousness of the 'Old' practitioners. In this case, from 'tithing' to 'generous offerings' from the church, that every time a collection is required by in their meetings, believers must be ready with theirs, which has been put aside, for when they are needed.
In the Gospel, JESUS said to HIS disciples, while they were watching the 'offerings' being offered by the people of Israel in the Temple, that the rich gave their 'silvers' and they gave out of their 'abundance', but the widow what she had for that day, she gave them all away and have nothing for later or tomorrow.
If Christians think they are wise in 'tithing', let me remind whether you first of all understand the truth knowledge of 'tithing'?
For example, even if you own a brand new car, 10 percent of the price of that new car goes to GOD as an offering of 'thanksgiving'. How about the others you own as well, because of the 'kindness' of GOD.
In similarity in this world where the Government impose tax on it's citizens that tax is required on every purchases and all incomes.
Thank you and may GOD the FATHER of our LORD JESUS CHRIST bless you with HIS kindness and peace.
