In Chapter 11 of Freak the Mighty, Kevin and Max travel to the New Tenements to deliver the purse to the damsel in distress. Tenements are run-down, overcrowded apartments in the poor section of the city. Everyone in town calls the New Tenements the New Testaments. Testaments are a covenant between God and man.
Rodman Philbrick uses irony to compare the violent, drug-infested tenements to the hope and joy of the New Testament in the Bible. It makes sense in the context of a story about Kevin who lives a better life in his imagination than the stark reality of his world. What will they find in the tenements?
The address on the ID card indicates that Loretta Lee lives in the New Tenements, or New Testaments as everyone calls it, on the other side of the millpond. Max is not allowed to go there, not that he wants to go. Only the poorest people and drug users live in the Testaments.
Kevin says that it's okay for Max to break his promise to Grim and Gram if he is on a quest. Kevin hopes for a reward, but Max knows better than to expect that at the Testaments.
On the way to the Testaments, Kevin rides on Max's shoulders as he does most of the time these days. Max likes having a big brain up top, and Kevin likes not having to use his braces or crutches.
When they arrive and Kevin sees how sad the New Testaments are, he is ready to give up on this one, but Max says since they're here, they should return the purse they found to its owner.
