retained something of its dominant rôle till the 11th century, had been founded, Sura by Abba Arika (q.v.) (c. 219), but Nehardea, the more ancient seat of the two, famous in the 3rd century for its association with Abba Arika's renowned contemporary Samuel, lost its Jewish importance in the age of Mahomet. To Samuel of Nehardea (q.v.) belongs the honour of formulating the principle which made it possible for Jews to live under alien laws. Jeremiah had admonished his exiled brothers: "Seek ye the peace of the city whither I have caused you to be carried away captives, and pray unto the Lord for it: for in the peace thereof shall ye have peace" (Jer. xxix. 7). It was now necessary to go farther, and the rabbis proclaimed a principle which was as influential with the synagogue as "Give unto Caesar that which is Caesar's" became with the Church. "The law of the government is law" (_Baba Qama_ 113 b.), said Samuel, and ever since it has been a religious duty for the Jews to obey and accommodate themselves as far as possible to the laws of the country in which they are settled or reside. In 259 Odenathus, the Palmyrene adventurer whose memory has been eclipsed by that of his wife Zenobia, laid Nehardea waste for the time being, and in its neighbourhood arose the academy of Pumbedita (Pombeditha) which became a new focus for the intellectual life of Israel in Babylonia. These academies were organized on both scholastic and popular lines; their constitution was democratic. An outstanding feature was the _Kallah_ assemblage twice a year (in Elul at the close of the summer, and in Adar at the end of the winter), when there were gathered together vast numbers of outside students of the most heterogeneous character as regards both age and attainments. Questions received from various quarters were discussed and the final decision of the _Kallah_ was signed by the _Resh-Kallah_ or president of the general assembly, who was only second in rank to the _Resh-Metibta_, or president of the scholastic sessions. Thus the Babylonian academies combined the functions of specialist law-schools, universities and popular parliaments. They were a unique product of rabbinism; and the authors of the system were also the compilers of its literary expression, the Talmud.
