הֲכָזֶ֗ה יִֽהְיֶה֙ צ֣וֹם אֶבְחָרֵ֔הוּ י֛וֹם עַנּ֥וֹת אָדָ֖ם נַפְשׁ֑וֹ הֲלָכֹ֨ף כְּאַגְמֹ֜ן רֹאשׁ֗וֹ וְשַׂ֤ק וָאֵ֙פֶר֙ יַצִּ֔יעַ הֲלָזֶה֙ תִּקְרָא־צ֔וֹם וְי֥וֹם רָצ֖וֹן לַיהוָֽה׃
Ganito ba ang pag-aayunong pinili Ko, isang araw na pinahihirapan ng tao ang kanyang kaluluwa? Ang iyuko ba niya ang kanyang ulo na gaya ng tambo, at maglatag ng magaspang na sako at abo bilang kanyang higaan? Ito ba ang tatawagin mong pag-aayuno, at araw na kalugud-lugod sa Walang-Hanggan?
Rashi
Is it to bend Heb. הֲלָכֹף. This ‘hey’ is the interrogative. That is to say, “Perhaps I require bending the head like a fishhook (כְּאַגְמֹן)?” אַגְמֹן is a sort of bent needle with which they catch fish, and they call it ajjm in O.F.
Ibn Ezra
A day for a man to afflict his soul. Repetition of the same idea (a fast) in other words.
Rashi
Will you call this a fast Heb. הֲלָזֶה. An interrogative form. Therefore, the ‘hey’ is punctuated with a ‘hataf-pattah.’
