BEIT SHEMESH, Israel — Richard Lakin’s funeral on Wednesday was touching in the tiny, usual ways. His grown son tearfully recalled a man who began every morning with a banana and a chuckle. His teenage granddaughter thanked him for teaching her to ride a bike and, barely able to get the words out, “for watching ‘Charlotte’s Web’ endless times with me.”

There were also hints at the unusual circumstances of his death. The United States ambassador to Israel sitting in the chapel’s last row, the former member of Israel’s Parliament helping fill the grave with dirt. And the son, Micah Avni, asking in his eulogy, “How is it that such a beautiful person is struck down in such a brutal and horrific manner?”

Mr. Lakin, 76, was shot in the head and stabbed in the face and chest by Palestinian assailants on a public bus in Jerusalem at the height of this month’s violent uprising. An American who moved to Israel three decades ago, he died after two weeks in the hospital, where he had much surgery and a parade of visitors, including Mayor Bill de Blasio of New York, Secretary General Ban Ki-moon of the United Nations and students from Hand in Hand, Jerusalem’s joint Arab-Jewish school.

He was one of nine Israeli Jews killed by Palestinians since Oct. 1. One of the two bus attackers was among more than 25 Palestinian suspects shot dead by Israelis during the same period; some 35 other Palestinians have been killed in clashes with security forces.
