But no, I swear by what you see.
I swear by what you se
I swear by all that you can see
But nay! I swear by that which you see
So I do not swear/make oath with what you see
I (God) swear by whatever you see
So by oath of the things you see
But nay, I swear by that which you see
So I swear by the things that you see
But nay! I call to witness those (signs) which you see
So I swear by whatsoever you see
