הֵ֣ן לְרִ֤יב וּמַצָּה֙ תָּצ֔וּמוּ וּלְהַכּ֖וֹת בְּאֶגְרֹ֣ף רֶ֑שַׁע לֹא־תָצ֣וּמוּ כַיּ֔וֹם לְהַשְׁמִ֥יעַ בַּמָּר֖וֹם קוֹלְכֶֽם׃
Lihatlah, kamu berpuasa untuk bertengkar dan berbantah, dan untuk memukul dengan tinju kefasikan. Kamu tidak berpuasa sebagaimana mestinya pada hari ini, supaya suaramu didengar di tempat tinggi.
Rashi
Do not fast like this day like the manner of this day, to break your hearts in order that your voice be heard on high.
Ibn Ezra
אגרף Some hard thing to strike with.5A. V., First. In this sense it is used in Rabbinical literature. Comp. בעלי אגרפין men with force (Pesachim 53); compare besides באגרף (Ex. 21:18).6In his commentary on Ex. 21:18, I. E. mentions this comparison in the name of Saadiah, while the other explanation, introduced here by the words, Others render it, is given, in his abridged commentary on Ex. 21:18, as his own, introduced by the word ויתכן, It is also right to say. Others7Very probably R. Jonah is meant, whose explanation is quoted in the commentary of I. E. on Ex. 21:18; he derived the word from the root גרף to sweep. render it a piece of hard earth, and connect it with מגרפותיהם their clods (Joel 1:17).
