Tithe Biblical Fact 1: Do you know that before the law, under the law and after the mosaic law until to date money was already in used? As a matter of biblical fact, tithe can be buy back under the law but plus 20% of its value. Say, your crops of 10% is worth 100dollar, should you wish to buy it back after giving the tithes to the levites, you have to pay 120dollar in return. This becomes not 10% or tithe rather it become 12%. Obviously tithe simple means 10% not 12%. In short, for a buy back to happen, a tithe of crops must be given first then buy it back but more than it’s original value. This is implied in the Lev 27:31 just after Lev 27:30 which implied that all the tithe of the land whether it be seed or fruits of the tree are holy to God and therefore tithable.
“All tenth-part gifts from the land, whether of seed from the ground or fruit from the trees, belong to the Lord; they are holy to the Lord.” Leviticus 27:30 CEB
“If someone wishes to buy back part of their tenth-part gift, they must add one-fifth to it.” Leviticus 27:31 CEB
In fact, if you read Lev 27 whole chapter, you’ll find out that it was not only the tithe of crops that can be redeemed, it includes but not limited to firstborn of unclean animals.
“But the firstborn of the animals, which should be the LORD’s firstborn, no man shall dedicate; whether it is an ox or sheep, it is the LORD’s. And if it is an unclean animal, then he shall redeem it according to your valuation, and shall add one-fifth to it; or if it is not redeemed, then it shall be sold according to your valuation.” Leviticus 27:26-27 NKJV
Think about this one, if tithe can be money, it wouldn’t make sense if someone wish to redeem it. Imagine, you earn 1000$ you tithe 100$, and if you wish to redeem your tithe, you have to payback 120$. Why would you buy back your 100$ tithe and then pay back 120$- an increase of 20% from the original value? On top of that it become not 10% anymore or tithe, it became 12%.
