Kaparot

It is an ancient custom on Erev Yom Kippur (or the days in between Rosh Hashana and Yom Kippur) to perform Kaparot with a chicken, or alternatively with money. The value of the chicken or the money is given to charity.

"Children of man who sit in darkness and the shadow of death, bound in misery and chains of iron - He will bring them out of darkness and the shadow of death, and will sunder their bonds. Foolish sinners, afflicted because of their sinful ways and their wrongdoings; their soul loathes all food and they reach the gates of death - they cry out to the Lord in their distress; He saves them from their afflictions. He sends forth His word and heals them; He delivers them from their graves. Let them thank the Lord for His Kindness, and [proclaim] His wonders to the children of man. If there be for a man [even] one interceding angel out of a thousand [accusers], to speak of his uprightness in his behalf, then He will be gracious to him and say: Redeem him from going down to the grave; I have found expiation [for him]."

"This is my exchange, this is my substitute, this is my expiation. This money shall go to Tzedaka and I shall proceed to a good, long life and peace."
