The officials who spoke of the prospect of a temporary freeze said the issue was explosive in Israel, so they were not prepared to have their names publicly associated with the idea at this stage. But they spoke with clear authority. They calculated that about 2,000 buildings were going up in West Bank settlements now and said that they would be completed under their proposal, but nothing new would start. They also said that if broader peace efforts came to naught, the building would start up again.

Mr. Barak himself declined to address the question of a temporary freeze in a conversation on Sunday with The New York Times, saying only that settlements should be viewed as one issue in a larger framework needed to create a Middle East peace.

“For us, it is very important that the Palestinians commit to seeking an end to the conflict and a finality of any claims,” he said. “We should not isolate this issue of settlements and make it the most important one. It has to be discussed in the context of a larger peace discussion.”

He added, “Many Israelis fear that what Palestinians want is not two states but two stages,” meaning an end to Israel in phases. He also said that by focusing solely on settlement building and not on what the Arab countries should also be doing for peace, Israel felt that it was being driven to its knees and delivered to the other side rather than asked to join a shared effort.

Israel, he said, was eager for a regional agreement that would lead to a state for the Palestinians and security for Israel.
