Well, if you can read paleo-Hebrew that sure looks like:

[לישׁעיה[ו]

נבי[א

as in:

ל = “belonging to”

[ישׁעיה[ו] נבי[א= Isaiah the prophet (with some letters missing)

We’ll see. I can hardly wait for the minimalist crowd to come up with another “what you see really isn’t what you see” argument. They’re good at that.

You can read a bit about the discovery here.
