Midrash su Salmi 87:5

(Fol. 75) (Ps. 87, 5) But of Zion it shall be said: "This man and that was born in her; and Most High Himself doth establish her." R. Meyasha, the grandson of R. Joshua, said: "No matter whether he is one who was born in it, or one that looks forward and hopes for its restoration [to both of them refer the passages with its promise."] "And one of them from the land of Israel," added Abayi, "is better than two of us [of Babylon."] "Nevertheless," remarked Raba, "if one of ours comes up here (in the land of Israel) he surpasses two of their in wisdom, as the instance of R. Jeremia who, before he came up there, did not understand what the Rabbis would say, but after he had been there he called us 'foolish Babylonians.' "
