Ma'aser Sheini 5:15
Ma'aser Sheini5: 15
יוֹחָנָן כֹּהֵן גָּדוֹל הֶעֱבִיר הוֹדָיוֹת הַמַּעֲשֵׂר. אַף הוּא בִטֵּל אֶת הַמְעוֹרְרִים וְאֶת הַנּוֹקְפִים. וְעַד יָמָיו הָיָה פַטִּישׁ מַכֶּה בִירוּשָׁלַיִם. וּבְיָמָיו אֵין אָדָם צָרִיךְ לִשְׁאֹל עַל הַדְּמַאי.
Yochanan Kohen Gadol brought to an end [the recitation of] the maaser declarations. And he also abolished the awakeners and the cutters. Until his days the hammer would bang in Jerusalem. And in his days, it was not necessary for anyone to in-quire about demai.
