Kraft, who is Jewish, paid his respects at the site of the shooting that saw 11 people killed and several others injured by a gunman on Oct. 27. The attack at the Synagogue is in the neighborhood of Squirrel Hill, which is a few miles from the Steelers' practice facility.
The 77-year-old Kraft then attended services with the congregation at its temporary location -- Rodef Shalom -- along with his son, Josh.
The elder Kraft accepted the invitation of the rabbi to speak to the congregation. He noted that it meant more to him to be with the congregation than the outcome of Sunday's game between the Patriots (9-4) and the Steelers (7-5-1).
Kraft then provided a boy, Max -- who was having his bar mitzvah -- with four tickets to the game at Heinz Field.
Kraft is a member of the Temple Emmanuel synagogue in Massachusetts.
Patriots wide receiver Julian Edelman acknowledged the significance of being in Pittsburgh by tweeting out the names of those killed in the shooting. Edelman's father, Frank, is Jewish.

Edelman tweeted out a picture of the cleats he plans to wear. One of the cleats has the Star of David on the ankle with the hashtag "#StrongerThanHate," while the other has the Tree of Life Synagogue logo.
"My heart is broken for the families in Pittsburgh," Edelman tweeted back in October in the aftermath of the shooting. "It's hard to even imagine such senselessness. As a Jew, an American and a human, I'm devastated. We are with you, Pittsburgh."
