The posuk says ‘u’k’shartem’ (you shall bind them) , not “v’hinachtem’ (you shall place them) – indeed, we routinely call it “putting on tefilin” = “hanachas tefilin”, rather than the way the Torah calls it: “keshiras tefilin”..
Well then, I guess I must be a complete idiot and am ha’aretz, since I have never made the bracha of “asher kidishanu b’mitvosav, vitzivanu, l’kasher tefillin.”
Thank you for educating me.
