Her arczt thut euch selbir rat
Mr. Physician, help yourself(1)|
with your masterly deed.
I'm leading you to Death's fellows,
who want to dance with you.
Ich habe myt meynem harnschawen
I have with my urine-watching(2)|
made man and women sound.
Who will now make me sound?
I am wounded to death.

The proverb that Luke refers to is probably Aesop's fable about the The Quack Frog: »A Frog proclaimed himself a physician. A Fox asked the Frog how he can cure others when he can't cure his own wrinkled appearance. Physician, heal thyself«.
Notice, how the doctor in the picture above drops his urine glass to the ground.
