"Hi, Sir. Someone has been stealing from me fairly regularly. My gut instincts tell me it's someone nearby. A well meaning friend taught me to write this spell on 2 pieces of paper and paste one at the back of the door and the other under the door. Question: I'm want to know that the spell means before I do it. Would you be able to translate this for me?

By Isaac [(or In the name of Isaac) sic, should be Esau]/
Who was the savior of Jacob and carried their house/
The guilty will be (punished with) short steel (i.e., a dagger)/
