After he had bestowed his blessing upon them, he asked them to propose capable pious men, that he might appoint them as judges and leaders over them. He said: "If a man were to present himself to me as a candidate for this position of honor, I alone should not be able to decide to what tribe he belonged, and whence he came; but you know them, and hence it is advisable for you to propose them. Do not think, however, that I feel I must abide by your choice, for it depends solely upon me, whether or not I shall appoint them."
