Talmud do Ezechiela 36:17

Rebbi Ammi asked Rebbi Simeon: Did you hear that one ordains Elders outside the Land? He answered, I heard that one does not ordain Elders outside the Land. Rebbi Levi said, is that not an explicit verse (Ez. 36:17): “Son of man, the House of Israel are dwelling on their Land;” that all your academies⁶³Taking the word ישב “to sit” in the meaning: “To study in a talmudic academy.” shall only be on your Land. The rabbis of Caesarea say, one may ordain Elders outside the Land on condition they return. Rebbi Isaac bar Naḥman was in Gaza and they ordained him on condition he return⁶⁴The Southern border of the Amoraic Land of Israel was Ascalon (cf. Ševi‘it p. 496.). Rebbi Zemina was in Tyre and they ordained him on condition he return. Also Rebbi Jonah was on the list but he refused to be ordained as long as his teacher was not ordained. They ordained his teacher. Rebbi Ḥama said, Jehudah ben Titus⁶⁵A fourth-generation Amora. was in Rome and they ordained him on condition he return.
