What hast thou to do with me, old Jephthah?

Illusions?  Allusions?  Both?  I'm reposting this letter from a reader:

Dear Professor Litvin
You might be interested in my discovery of a subtle illusion in Hamlet to the (ancient) Middle East war. As I explain on my website, Hamlet’s mention of “old Jephthah” is meant to point to these lines in the Biblical story of old Jephtha: Judges 11.12
… What hast thou to do with me, that thou art come against me to fight in my land?
Judges 11.13
…Because Israel took away my land… now therefore restore those lands again
I discuss this, and it’s connection with the Spanish Armada, on my free and and ad-free website, “Smith’s Hyper Hamlet”, www.thyorisons.com.
