Crescas was a man of means. As such he was appointed sole executor of the will of his uncle Vitalis Azday by the King John I of Aragon in 1393. Still, though enjoying the high esteem even of prominent non-Jews, he did not escape the common fate of his coreligionists. Imprisoned with his teacher upon a false accusation of host desecration in 1378, he suffered personal indignities because he was a Jew. His only son died in a massacre in Barcelona in 1391, a martyr for his faith, during the anti-Judaic persecutions of that period. Nevertheless, he kept his faith.
