Short answer: Yes And for those who like the details: The U.N. partition plan, Resolution 181(II), would have created independent Arab and Jewish states, with Jerusalem under international control. The Jewish Agency for Palestine, which represented the Jewish side in official negotiations, accepted the plan; the Arab side rejected it. A few hours before the British mandate was due to expire on May 15, Jewish leaders declared the establishment of the State of Israel. The Israeli Declaration of Independence included the following wording: The State of Israel is prepared to cooperate with the agencies and representatives of the United Nations in implementing the resolution of the General Assembly of the 29th November, 1947 ... We appeal to the United Nations to assist the Jewish people in the building-up of its State and to receive the State of Israel into the comity of nations. https://avalon.law.yale.edu/20th_century/israel.asp So while the U.N. did not actually give any land to Israel because the partition plan was never implemented, it seemed to the founders of Israel, subsequent governments and most of its citizens today that the plan formed the basis of the State of Israel under international law. In that sense, the U.N. gave Israel some of its current land. Times change. The vote on the partition plan was in israel's favor, many later resolutions weren't.
