"We know that the pope is going to a particularly suffering land," Cardinal Pietro Parolin, whose role is equivalent to that of a prime minister, told Vatican television ahead of the pope's three-day visit starting on Saturday.
"I really hope that the fruit will be to help politicians and all people of good will take courageous decisions on the path to peace," Parolin said in the interview, which was posted on the website of Vatican Radio.
"On the one hand, Israel's right to exist in peace and security within internationally recognised boundaries.
"And the Palestinian people's right to have a homeland, sovereign and independent, the right to move around freely, the right to live in dignity," he said.
The pope travels to Jordan first on Saturday where he will meet Syrian refugees, then to Bethlehem in the Palestinian Territories on Sunday and on to Jerusalem where he will hold a prayer for Christian unity and visit holy sites.
The Vatican recognised the Palestinian Territories as the "State of Palestine" in 2012 and has incurred Israeli ire in the past for appearing to side with the Palestinians although relations have improved markedly in recent years.
