An Israeli man blows a Shofar during prayers by the HaYarkon River in Tel Aviv as he performs the Tashlich ceremony. Tashlich (&quot;casting off&quot;), is a Jewish custom performed on the afternoon of Rosh Hashanah at a water source. It is customary to throw pieces of bread into a large, natural body of flowing water to &quot;cast away&quot; the sins of the past year and resolve to be a better person in the year to come.
