פרשת האזינו תש"ה - השירה

I thought I would make an end of them, I would make their memory cease from among men;

אמרתי אפאיהם means, I said in my heart, “I will אפאה them”. One may explain אפאיהם to mean: I would make them as פאה, i.e. “as grain left in the corner of the field”, to cast them away from Me as something free to all. We find a similar idea to this in Ezra (Nehemiah 9:22), “And thou gavest them kingdoms and nations and didst set them aside as a corner (פאה)” — i.e., as free to all. Thus (under this meaning) did Menachem ben Seruk classify it. Others expound it as the Targum does: My wrath (אף) will fall upon them. This is, however, not correct, for if it were so (i.e., if אפאיהם were connected with אף) it ought to have written אֲאַפְאֵיהֶם with two Alephs, the one as a servile letter (a prefix) and the other as a root letter, just as in (Isaiah 45:5) אאזרך, “I girded thee”, and (Job 16:5) “I would strengthen you (אאמצכם) with my mouth” (in both these cases the first letter of the root is א as it is in אף), and the middle א (that after the פ) would not be proper to be in it at all. Onkelos, however (in connecting the word with אף, anger), rendered it according to the explanation of a Baraitha taught in Sifrei Devarim 322:1 which divides this word into three words, אמרתי אף אי הם, which means, I said in My anger (אף) I will make them as though they were not existent, i.e., that those who are looking for them would ask about them, “Where are they (אי הם)?".
