The law, which came 430 years afterward, does not set aside the covenant previously established by God

In some languages it might be strange to speak of a law coming or setting aside a covenant. It might be clearer to make explicit who gave the law. Alternate translation: "When God gave the law 430 years later, he did not set aside the covenant that he had previously established" (See: rc://en/ta/man/translate/figs-explicit)

set aside

"cancel"

430 years

"four hundred and thirty years" (See: rc://en/ta/man/translate/translate-numbers)
