פירוש על עבודה זרה 146:6

The problem with R. Yirmiyah’s statement is that Abaye said that R. Eliezer permits the mixture only if they first remove the prohibited leaven before the permitted leaven falls in together. But if they do not, then the prohibited leaven joins the permitted leaven to make the whole mixture prohibited. But this is not like Hizkiyah for Hizkiyah allows the mixture even if the prohibited wine is still there. Therefore, the equation of Hizkiyah and R. Eliezer falls apart.
