What Book of Mormon character delivered a sermon while standing on a wall?


Samuel the Lamanite

And it came to pass that they would not suffer that he should enter into the city; therefore he went and got upon the wall thereof, and stretched forth his hand and cried with a loud voice, and prophesied unto the people whatsoever things the Lord put into his heart. And he said unto them: Behold, I, Samuel, a Lamanite, do speak the words of the Lord which he doth put into my heart; and behold he hath put it into my heart.... Helaman 13:4-5
