פירוש על דמאי 4:1

Reading of all manuscripts, Mishnah and Yerushalmi. In the Venice print by mistake: Eleazar.

This word only appears in the Leyden ms and universally is declared a scribal error. However, the argument given at the end of the first paragraph of the Halakhah shows that it is genuinely part of the Yerushalmi Mishnah.
