If you are talking about the first of the ten commandments in Exodus, then they would be:
1. You shall have no other gods before me
2. You shall have no idols
3. You shall not take the Lord's name in vain
4. You shall remember the Sabbath and keep it holy
5. Honor your father and mother
These are in my own words, but the reference is Exodus 20:3-12 if you would like to quote them word for word. I highly recommend reading them all!
According to Kennedy's address, the idea that must be changed is that black people are less worthy than white. Basically, it's an idea that freedom has limits. If freedom exists in the United States, it must exist and be applicable to everyone, including the African American citizens. If it excludes anyone, based on any feature, it is not freedom at all. Freedom is the basis of American Constitution. It is one of the pillars of American national identity. So, it must be available and guaranteed for everyone. The change is necessary because it is time to start employing this idea that had been abstract for an entire century. By changing this idea, the American society would become a society of equals, with each and every citizen's fundamental human rights being protected and guaranteed.

It means that if you do not speak up about being depressed or "in pain" people around you that you interact with will unknowingly kill you on the inside and when/if you speak up they will assume you enjoyed it because you did not speak up before. Its a metaphor you see... if someone were to continuously stab you and you didnt speak up, they would stab you to death and assume you liked it for not acknowleding your pain.
