Helaman 10:14

therefore Nephi did declare unto them the word of the Lord, saying: Except ye repent, thus saith the Lord: Ye shall be smitten even unto destruction.—

So Nephi told them the Lord’s message. He said: 'Unless you change, this is what the Lord says: You will be destroyed.'

So Nephi declared the Lord’s message again: 'Unless you turn from your sins, the Lord says you’ll be destroyed.'
