הֵ֣ן לְרִ֤יב וּמַצָּה֙ תָּצ֔וּמוּ וּלְהַכּ֖וֹת בְּאֶגְרֹ֣ף רֶ֑שַׁע לֹא־תָצ֣וּמוּ כַיּ֔וֹם לְהַשְׁמִ֥יעַ בַּמָּר֖וֹם קוֹלְכֶֽם׃
Behold, ye fast for strife and contention, And to smite with the fist of wickedness; Ye fast not this day So as to make your voice to be heard on high.
Targum Jonathan on Isaiah
Behold, ye fast for provocation and strife, and to smite with the fist of wickedness; ye shall not fast a fast as if to make your voice to be heard on high.
