Haim Habib, 78, has been named as one of two fatalities in the stabbing and shooting attack on a bus in the capital's Armon Hanatziv neighborhood on Tuesday.
Habib's wife, Shoshana, remains hospitalized in serious condition in Shaare Zedek Medical Center in Jerusalem.
Police concluded on Tuesday evening that two Israelis were killed and seven more injured in the attack perpetrated by two Arab terrorists.
The two terrorists, residents of Jabel Mukaber in eastern Jerusalem, entered the bus armed with a pistol and two knives.
After the terrorists began to stab and shoot passengers, the bus driver opened the doors of the bus allowing some civilians to escape.
One of the terrorist then ran to the driver's seat and locked the doors before continuing to harm passengers.
A police patrol car from the Oz station arrived on the scene and along with Border Police quickly identified the terrorists on the bus. They fired at the two assailants and disarmed them.
Baha Alian, 23, a Fatah terrorist who had previously expressed pro-terrorism views, was shot and killed by security forces at the scene.
The second assailant is a Hamas terrorist who was jailed for his involvement with the terror group in 2013-14. He was wounded and taken into Israel Police custody for questioning.
Rabbi Yeshiyahu Krishevsky, 59, was the first Israeli victim to be named after two deadly terror attacks in the capital on Tuesday. He was murdered in a combined car and stabbing attack in Jerusalem's Geula neighborhood.
