and let me go

"so I can go"

you know the service I have given you

Jacob is reminding Laban of their contract (Genesis Gen 29:27). The abstract noun "service" can be stated as "served." Alternate translation: "you know that I have served you long enough" (See: rc://en/ta/man/jit/figs-abstractnouns)
