ears and mouths

The other week, in Exodus 13, I wrote the verse

והיה לך לאות על ידך ולזכרון בין עיניך למען תהיה תורת יקוק בפיך
It shall be a sign upon your hand and a remembrance between your eyes, in order that God's Torah shall be in your mouth...

This is the verse whence we derive that the Torah is to be written only with materials from kosher species (more about that here).

A few chapters later, in Exodus 17, God says to Moses:

ויאמר יקוק אל משה כתב זאת זכרון בספר ושים באזני יהושע
...Write this for a remembrance in a book, and put it in the ears of Joshua...

and one wonders what the Torah would look like had we chosen to take this verse literally as well.
