The structure and meaning of a sentence

The text below is from the Hemingway's book, "For Whom The Bell Tolls."
In that underlined part, I cannot figure the structure of this sentence as well as what that part exactly means. To me, for example, 'this and that' seems verb but I'm not 100% sure about it.

Now we come for something of consummate importance and thee, with thy dwelling place to be undisturbed, puts thy fox-hole before the interests of humanity. Before the interests of thy people. I this and that in the this and that of thy father. I this and that and that in thy this. Pick up that bag.”

In an website, there was a helpful comment as follows; One of Hemingway's solutions was simply to quote the original Spanish word or phrase. It's then up to the reader to check with a Spanish/English dictionary to learn how crudely someone has insulted someone else.
A second method was to employ an all-purpose and acceptable English word that at least suggests the original. Anselmo, in his early tirade about Pablo's negative attitude, says: “I this and that in the this and that of thy father. I this and that and that in thy this.”

Thanks to this site, I now know the underlined part is criticizing harshly Anselmo. Anyhow, I need to know the structure of this sentence as well as what that part exactly means.

Thanks in advance.
