The term 'Hebrew Leaders' refers to the Alephs, which are the first letter of the Hebrew alphabet. Alephs were traditionally used to refer to the leaders of the Jewish people, such as the High Priest and the King. They were also used to refer to the Patriarchs of the Bible, such as Abraham, Isaac, and Jacob. In modern times, Alephs are still used to refer to important figures in the Jewish community, such as rabbis and scholars.
