An angel chastises Laman and Lemuel in verse 29:
29 And it came to pass as they smote us with a rod, behold, an angel of the Lord came and stood before them, and he spake unto them, saying: Why do ye smite your younger brother with a rod? Know ye not that the Lord hath chosen him to be a ruler over you, and this because of your iniquities? Behold ye shall go up to Jerusalem again, and the Lord will deliver Laban into your hands.This incident is referenced by Nephi in 1 Nephi 7:10:
10 How is it that ye have forgotten that ye have seen an angel of the Lord?
