Halo 5 Art Puzzle Hidden Message?

If you look closely at the space above Chief’s head (where the arch of a doorway(?) is) it looks like there’s a couple words hidden but I can’t read it. Can anyone read it and what do you guys think about it? Please discuss.

(Note: You should zoom in on your screen as far as you can when you look at the picture.)

I read the title as massage, like… to receive a deep tissue back massage. Made me lol.

it just looks like some covenant script

I zoomed in and couldn’t find anything.
