Fast reflexes and quick thinking from one man may have saved the Monsey tragedy from becoming the Monsey massacre last Saturday.

Officials recognized Rockland resident Joseph Gluck for his bravery and credited him for saving countless lives.

As Grafton Thomas allegedly stabbed and slashed at five Hasidic Jewish men at a Monsey shul on the seventh night of Hanukkah, Gluck first helped others escape and then went after the suspect.

He threw a table at Thomas, stopping the attack at that moment.

Rep. Nita Lowey presented him Tuesday with a congressional certificate.

"And as the assailant entered Rabbi Rottenberg’s home, Josef confronted him and physically interfered in his availing to hurt more people,” said Lowey.

Gluck quickly wrote down Thomas' license plate number as he got into his car to escape. He shared the information with police who captured Thomas' tag crossing the George Washington Bridge.

He was arrested two hours later in Harlem.

Gluck is also expected to receive an award from the state Senate this weekend.
