New York Gov. Kathy Hochul’s 87-year-old father died overnight while she was touring Israel — with the emotional politician leaving a note paying tribute to him in the Western Wall early Thursday.

“I pray for my father, who cherished his visit to this Holy Land, and who passed during the night,” Hochul’s handwritten message read in part.

Hochul was dressed in all black to mourn dad John Courtney, who died from a brain hemorrhage in Florida Wednesday night.

Courtney was an Irish Catholic who had previously visited Israel and encouraged his daughter to do the same.

Hochul arrived in Israel Wednesday in a show of support for the country and its people in the wake of the deadly Oct. 7 atrocity by Hamas terrorists.

After meeting with families of hostages being held in Gaza and with volunteers at a food pantry, the Democrat traveled to Jerusalem and stayed there overnight.

On her visit to the Western Wall, known as the holiest site in Judaism, a somber Hochul penned a letter sending up a prayer for her father and for the victims of the conflict raging in the Middle East.

In accordance with tradition, Hochul tucked her letter into a crack in the ancient wall — the last remnant of the original retaining wall that surrounded the Second Temple built over 2,000 years ago.

“As I stand at this holy site, I pray that the arc of the universe bend toward justice, and may God continue to protect us and guide us to a peaceful, violence-free future,” the governor wrote.

“I pray for the victims of the Hamas attack on Israel, their families and all the innocent civilians lost as a result,” the note continued. “I pray for my father, who cherished his visit to this Holy Land, and who passed during the night.”
