תן לי יבנה וחכמיה ושושילתא דרבן גמליאל
Give me Yavneh and her Sages and the line of Rabban Gamliel
,ושושילתא דרבן גמליאל - משפחת הנשיא שלא תהרגם שלא תכלה שולטנות בית דוד:,
The line of Rabban Gamliel: That he was of the family of the Nasi (prince/President) of the Sanhedrin, and that this line should not be killed or consumed, as they were the descendants of the House of David who were destined to rule Israel.
The Jewish Encyclopedia, Rabban Gamliel II
The recognized head of the Jews in Palestine during the last two decades of the first and at the beginning of the second century. He continued with great energy and success the work of restoration begun by Johanan b. Zakkai…Perhaps it was Gamaliel II. to whom the title of "nasi" (prince; later replaced by "patriarch") was first given to raise him in public estimation and to revive the Biblical designation for the head of the nation. This title later became hereditary with his descendants. Gamaliel was officially recognized by the Roman authorities; and he journeyed to Syria for the purpose of being confirmed in office by the governor...
The guiding principle in all of Gamaliel's actions is set forth in the words which he spoke on the occasion of his quarrel with Eliezer b. Hyrcanus (B. M. 59b): "Lord of the world, it is manifest and known to Thee that I have not done it for my own honor nor for that of my house, but for Thy honor, that factions may not increase in Israel." The ends which Gamaliel had in view were the abolition of old dissensions, the prevention of new quarrels, and the restoration of unity within Judaism. To attain these objects he consistently labored to strengthen the authority of the assembly at Yavneh as well as his own, and thus brought upon himself the suspicion of seeking his own glory...
Gamaliel took care that the decisions reached by the assembly under his presidency should be recognized by all; and he used the instrument of the ban relentlessly against obstinate opposers of these decisions. He even placed his own brother-in- law, Eliezer b. Hyrcanus, under the ban (B. M. 59b). Gamaliel forced Joshua b. Hananiah, another famous pupil of Johanan b. Zakkai, to recognize the authority of the president in a most humiliating way, namely, by compelling Joshua to appear before him in traveler's garb on the day which, according to Joshua's reckoning, should have been the Day of Atonement, because Gamaliel would suffer no contradiction of his own declaration concerning the new moon
