The rabbi wounded in a shooting at the Chabad of Poway synagogue spoke at the White House Thursday during a National Day of Prayer service.
President Trump also honored those who rushed in to stop the shooter.
"We are privileged to be in the presence of heroes who raced after the murderer and helped disrupt the attack at the Poway synagogue," Trump said. "Army Veteran Oscar Stewart and Border Patrol Agent Jonathan Morales."
One woman was killed and three others wounded by a gunman at the synagogue on Saturday. Oscar Stewart chased the shooter out of the synagogue.
"We need to be strong," Stewart said. "That’s the only way we’re going to defeat evil and do not be afraid to be who you are. Be proud and lift yourself up."

Off-duty U.S. Border Patrol agent Jonathan Morales fired shots at the suspect as he fled the synagogue.
"We were celebrating the last day of Passover — supposed to be a joyous and festive event and we were attacked with our backs turned," Morales said. "But brave people stood up and confronted this person and we ended this situation as best we could with the resources we had."
Rabbi Yisroel Goldstein was shot and lost a finger during the attack.
"Just five days ago Saturday morning I faced evil and the worst darkness of all time right in our house of worship right in the Chabad of Poway," Goldstein said.
The rabbi thanked Trump for offering his support and honoring the woman who was killed.
"Mr. President when you called me I was at home weeping — you were the first person who began my healing," Goldstein said. "You heal people in their worst of times and I am so grateful for that. You have helped me bring great honor to Mrs. Lori Kaye a 60-year-old dear friend of our congregation."
