Hebrew etymology[edit]
The Hebrew word Ḥasīd appears for the first time in the Torah (Deuteronomy 33:8) with respect to the tribe of Levi, and all throughout the Hebrew Book of Psalms, with its various declensions.[2] In classic rabbinic literature it differs from "Tzadik" ("righteous") by instead denoting one who goes beyond his ordinary duty. The literal meaning of Ḥasīd derives from Chesed (חסד) (= "kindness"), the outward expression of love (lovingkindness) for God and other people. This spiritual devotion motivates pious conduct beyond everyday limits. The devotional nature of its description lent itself to a few Jewish movements in history being known as "Hasidim". Two of these derived from the Jewish mystical tradition, as it could tend towards piety over legalism.
Rabbi Saadia Gaon, the medieval Hebrew linguist and biblical exegete, translated the Hebrew word Ḥasīd in Psalm 18:25 into the Judeo-Arabic word אלמחסן, meaning, "he that does good."[3]
Usage in rabbinic texts[edit]
As a personal honorific, both "Ḥasīd" and "Tzadik" could be applied independently to the same individual with both different qualities. The 18th-century Vilna Gaon, for instance, at that time the chief opponent of the new Jewish mystical movement that became known as "Hasidism", was renowned for his righteous life. In tribute to his scholarship, he became popularly honored with the formal title of "Genius", while amongst the Hasidic movement's leadership, despite his fierce opposition to their legalistic tendencies, he was respectfully referred to as "The Gaon, the Ḥasīd from Vilna".
A general dictum in the Talmud (Baba Kama 30a) states: "He that wishes to be pious (Aramaic: ḥasīda), let him uphold the things described under the indemnity laws in the Mishnaic Order of Neziqin." Rava, differing, said: "Let him observe the things transcribed in Pirkei Avot." (ibid.)
Of the few known pious men in the early 2nd century, the Talmud acknowledges the following: "Wherever we read (in Talmudic writings), 'It is reported of a pious man', either R. Juda b. Baba it meant or R. Judah, the son of R. Ilai."[4]
In the aggregate, "Ḥasīd" may also refer to members of any of the following Jewish movements:
