Giving Charity
Tzedakah & chesed
On the verse “each shall give an atonement offering for himself” (Shemos 30:12), Rav Yechezkel Shraga pointed out that the Hebrew word for “each shall give,” venasnu, spelled vav, nun, tav, nun, vav, is a palindrome, spelled the same forward and backward. This teaches that whatever a person gives to charity will be returned to him. He will not lack anything for the charity he donates, and the more he gives, the more he will receive.
