Several
halakhot are preserved under Eleazar's name in the
Mishnah. He takes part in halakhic disputes with
Eleazar ben Azariah and
Rabbi Akiva and with
Eliezer ben Jacob I. 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. Some
aggadot also are ascribed to him. Together with Rabbi Joshua, he gives an allegorical reason for why
Amalek's attack on Israel occurred when it did. Citing
Job 8:11, "Can a rush grow up without mire? Can the flag grow without water?" he remarks, "Even so is it impossible for Israel to flourish without the Law; and since they had neglected the Law, an enemy was ordered out to war against them." Elsewhere, he cites
Isaiah 43:22, "But thou hast not called on me, O Jacob," and applies it to those who are not devout in their prayers, but communicate with their neighbors by sign language while reciting the
Shema. ==Scientific knowledge==
