a Benjamin's portion

Benjamin's portion

A particularly large portion (of something), or the largest portion given. A reference to Genesis 43:34, in which Joseph, the son of Jacob who was sold to the Egyptians and became a high-class official, treated his former brothers to a feast, with his youngest brother Benjamin receiving a portion five times that of the others. The phrase is used almost exclusively in reference to God or religion. When it comes to the love God gives us, we all have Benjamin's portion: many times more than we might have expected or felt we deserve.

a Benjamin's portion (or mess)

the largest share or portion.
In the Bible, Benjamin was the youngest son of the Jewish patriarch Jacob . When Jacob's sons encountered their long-lost brother Joseph in Egypt, where he had become a high official, they failed to recognize him, but Joseph generously entertained them: ‘And he took and sent messes [servings of food] unto them from before him: but Benjamin's mess was five times so much as any of their's’ (Genesis 43:34).
