Alma 26:10

And it came to pass that when Ammon had said these words, his brother Aaron rebuked him, saying: Ammon, I fear that thy joy doth carry thee away unto boasting.

When Ammon said these words, his brother Aaron told him he was wrong. Aaron said: Ammon, I’m afraid your happiness is making you brag.

After Ammon said all this, his brother Aaron stopped him. “Ammon, I’m worried your joy is making you boastful.”
