For other people named Eleazer. see: Eleazar (name)
Eleazar Chisma (Ḥisma; Hebrew: אלעזר חסמא, "Eleazar Chasma", or אלעזר בן חסמא, "Eleazar ben Chasma") was a tanna (sage) of the second and third generations (2nd century); he was a disciple of Joshua ben Hananiah and Gamaliel II. (Ḥag. 3a; Hor. 10a).
In their use of the word "ben" in connection with his cognomen "Ḥisma" or "Ḥasma" (see Geiger, "Schriften," iv. 343, and Strack, "Einleitung in den Thalmud," 2d ed., p. 81), the sources are inconsistent; its insertion, however, seems justifiable. "Ḥisma," is not an adjectival cognomen (see Eleazar I.), but a locative, the place probably being identical with Hizmeh (see Luncz, "Jerusalem," vi. 67; Selbie, J. A. (1898). "Azmaveth". In James Hastings. A Dictionary of the Bible. I. p. 208.; hence "ben Ḥisma" means "son of [= "native of"] Ḥisma" (compare R. H. 17a; Meg. 19a; Ḳid. ii. 3).
Several halakot are preserved under Eleazar's name in the Mishnah (Ter. iii. 5; B. M. vii. 5), and he is met with in halakic controversies with Eleazar ben Azariah and Rabbi Akiva (Neg. vii. 2; Sifra, Tazria', i. 2), and with Eliezer ben Jacob I (Pes. 32a; Yalḳ., Lev. 638); and to him is ascribed the economic rule that the employee is not entitled to a proportion of his employer's produce greater than the amount of his wages (B. M. vii. 5, 92a; Sifre, Deut. 266).
