For I say to you

This adds emphasis to what Jesus says next.

you ... your ... you

These are plural. (See: rc://en/ta/man/jit/figs-you)

that unless your righteousness exceeds ... Pharisees, you will in no way enter

This can be stated in a positive form. Alternate translation: "that your righteousness must exceed ... Pharisees in order to enter" (See: rc://en/ta/man/jit/figs-doublenegatives)
