Why does the binding of Isaac story use the unique term ע.ק.ד (ʿ.q.d)?Could be. But chiasm is a flexible tool. You can get pretty much what you want out of it. And the alliteration is not very close. Still, it's an interesting analysis.
For PaleoJudaica posts on the Aqedah (the Binding of Isaac in Genesis 22) see here and links. As noted there, I have published strong evidence that Genesis 22:14 originally named the place as "Elohim Yir'eh," not "YHWH Yir'eh." Cf. Prof. Rendsburg's point 8.
