One of the key themes the Torah reiterates over and over is the importance of charity:

עשר תעשר – you shall tithe… (14:22)

In Hebrew, a double statement means to do something repeatedly.

How can the Torah expect us to keep giving charity over and over?

Recognising the issue with giving charity to the point we have nothing left, the Gemara in Kesubos caps charity at no more than 20% of our income.

While this is a sensible limit dictated by necessity, we still need to make sense of the fact the Torah expects us to keep giving repeatedly.

Taking this at face value, the Vilna Gaon concludes that if the Torah truly requires endless generosity without depleting the giver, it can only be that the reward for charity is the ability to give more!

Indeed, this could be why the Gemara in Taanis says that עשר בשביל שתתעשר – a person who gives generously will receive blessings of abundance.

Learning to take better care of others is a fundamental principle that underlies the entire Torah. Our long tradition reassures us that like a candle doesn’t lose anything by lighting another candle, we will never be worse off for helping others.
