2 Nephi 5:21


21 And he had caused the cursing to come upon them, yea, even a sore cursing, because of their iniquity. For behold, they had hardened their hearts against him, that they had become like unto a flint; wherefore, as they were white, and exceedingly fair and delightsome, that they might not be enticing unto my people the Lord God did cause a skin of blackness to come upon them.

Thanks for the source. I looked it up and this is it.
2 Nephi 5:21
Book of Mormon

21 And he had caused the cursing to come upon them, yea, even a sore cursing, because of their iniquity. For behold, they had hardened their hearts against him, that they had become like unto a flint; wherefore, as they were white, and exceedingly fair and delightsome, that they might not be enticing unto my people the Lord God did cause a skin of blackness to come upon them.

I looked up what Mormon commentary was on it. Here it is

(Make sure students understand that the curse mentioned in this chapter was separation from God. The changing of the Lamanites’ skin was only a mark or sign of the curse.

• How does 2 Nephi 5:21 help you understand why the Lamanites were cut off from the presence of the Lord? (You may want to explain that flint is a hard stone. In saying that the Lamanites “had become like unto a flint,” Nephi emphasized the hardness of the Lamanites’ hearts. To be hard-hearted is to be unresponsive to the promptings of the Spirit of God.)
  
• What is a principle we can learn from 2 Nephi 5:20–24 that describes what happens when people harden their hearts against the Lord? (After students respond, write the following principle on the board: When people harden their hearts against the Lord, they separate themselves from Him.)
  
• What are some reasons why people may choose to harden their hearts against the Lord?
  

Encourage students to remember what they have determined they will do to live more fully “after the manner of happiness.” Express your confidence that they can follow the Nephites’ example and be truly happy.)
