Tashlikh (Hebrew: תשליך, meaning “casting off”) is a long-standing Jewish practice performed on the afternoon of Rosh Hashanah, the Jewish New Year. The previous year’s sins are symbolically “cast off” by throwing pieces of bread, or a similar food item, into a large, natural body of flowing water (such as a river, lake, sea or ocean).
The name “Tashlikh” and the practice itself are derived from the Biblical passage (Micah 7:18-20) recited at the ceremony: “You will cast all their sins into the depths of the sea.”
