Tapping into the resilience of Jewish culture and setting good intentions for the year ahead.
"While there are very challenging moments that we've been through and that we may be facing as well, fear doesn't help. And we put our faith in God and trust in God, and that carries us through. And we've been doing that for 3,500 years," he said.
Rosh Hasanah will officially begin on Wednesday night and last until sundown on Friday.
