history - Why do some of the Ten Commandments include Noahide Laws?

Of the Seven Noahide Laws, at least three are identical to one of the Ten Commandments. To be specific I am referring to

• Do not murder


• Do not steal


• Do not deny God


• Do not blaspheme

I understand that the Noahide Laws were in practice long before the Ten Commandments, so I assume the Israelites were already keeping these before the episode at Sinai.

My question is, why did some of these commandments need to be reincluded? Do the ten commandments override the Noahide laws?
