One of the students of Rabbi Yochanan ben Zakkai mentioned in Pirkei Avot (2:8), he is the R’ Yehoshua referred to throughout the Talmud. He was a man of fine personal attributes, regarding whom it is said “Fortunate is she who gave birth to him”. It is said that when his mother was pregnant with him, she would go to the study halls and ask the Torah scholars to pray for her unborn child that he should grow up to be a Torah scholar. After he was born, she would not remove his bed from the study hall, in order that he would always hear the words of Torah.
