The Talmud compares the goats of Yom Kippur, which were chosen by lottery, to an offering of a pair of birds, where one bird is an elevation offering and the other a sin offering. The identity of each bird can only be set at the time of their purchase or when the priest brings them as offerings. This is unlike the pair of goats which cannot be set at those times, only via the lottery.
This reminds us that when we purchase something we should have a specific purpose in mind. This sounds obvious, but as my own rabbi says: “modern culture pushes us to buy things we don’t need, with money we don’t have, to impress people we don’t like”.
Consumer culture indoctrinates us to spend more than we need to, so other people can make more profit. Before you make a purchase, evaluate exactly why you need this item, and how you will use it.
It is often a much better investment to spend your money on gaining knowledge and experiences. Spend on education, books, travel, dance lessons, music lessons, gym and martial arts memberships. Invest in yourself, not in stuff.

The bird offerings are used to fulfill certain obligations when a person cannot afford animal offerings (Leviticus 5:7, 12:8 and 14:21). These are the only times the Bible changes a man’s required expenditures based on his wealth. All other financial obligations are a set percentage – a flat tax.
The tithes are 10%, Trumah is not set in the Bible but Rabbinically established at 2%. In the Biblical “tax” regime, a man would be giving about 15% of his crops, and 10% of his animals, as the second tithe belongs to the owner to use in Jerusalem, and the tithe to the poor is given two years out of every seven.
When the ancient Jews established a monarchy, the king was also able levy taxes on the people at a 10% rate (I Samuel 8:15-17). Samuel the prophet tells the people this is exorbitant and akin to slavery. The total tax rate was then about 24% on crops and 19% on animals…
The big picture here is that in the Biblical worldview, a man who generates more money is getting a blessing from above, and is not to be punished by paying a larger percentage of his wealth in taxes. We do not believe that when a makes more should pay more of his earnings to the state to redistribute his money. In the Jewish view, when a man earns more he is not taking a bigger slice of the pie and leaving less for others, it is that God has made a bigger pie.
Money comes from God, and wealth gives a man an opportunity to give more charity and help build up his community, and invest in growing his business ventures for the benefit of everyone. When the state instead takes more money for its own purpose, that deprives men of their ability to choose where to allot their wealth.
We see that the Bible only changes your obligation for three specific offerings, as a leniency for poorer citizens. The Bible never says that a wealthy man pays more tithes or taxes. A man with 10 new animals that year gives one as the tithe, and a man with 10,000 gives 1000.
When you build yourself up into a stronger, smarter, and wiser man, and start earning more money, or seeing more success in life, this is an opportunity to reflect. Should you feel that your success is taking away from other men? That is a popular message in modern society – but it is the opposite of the Bible’s wisdom.
