(CNN) After a suspect stabbed five people at a Hanukkah gathering in suburban New York, a rabbi resumed the celebrations at a synagogue next door.

The Orthodox Jewish Public Affairs Council shared footage of Rabbi Chaim Rottenberg leading a room full of celebrants in rousing song after the event at his home was interrupted by the attack.

Attendees were members of Monsey's Hasidic Jewish community, a subgroup of Orthodox Judaism.

When the event resumed, the council said, the people there chanted, "The grace of God did not end and his mercy did not leave us."
