פירוש על ברכות 56:2

ONCE THE TIME [TO RECITE] THE AFTERNOON PRAYER HAS ARRIVED, A PERSON MAY NOT TASTE ANYTHING ETC. And R’ Yehoshua ben Laivee is of the opinion that as soon as the time for minchoh arrives we must even stop eating. And it is not so. We do not follow R’ Yehoshua ben Laivee in this matter.¹See Tosfos Shabos 9b matter. ד'ה בתספורת for a different opinion on this matter.
