Uncle Tom's Cabin chapters 18-19, help?

Eva says this twice in the novel, once on page 239, and once again 257. These words express her sadness because she's unable to verbalize her feelings in any other way.

I looked in my book of Uncle Tom's Cabin and I could not find the quot. My book is the Modern Library Edition, so could you please tell me what Eva is sad about?

Eva is sad with the inhumane justice of slavery. Each enslave individual are held into bondage without any proper bringing up and no complete understandings of the Bible. She wishes her father and other slave owners would release all servants from bondage and remain good in order to reach God's heavenly kingdom. Even though Eva is dying, she refuses to think about herself. She "truly" loves and adores all servants; including Topsy and Uncle Tom and dreams for them their freedom.
