To paraphrase the pride of Noah, he is saying, in effect, "who does the Lord think he is?" "Why should a king as great as I be worried about the Lord?" His attitude represents the opposite of "fear of the Lord." He has no fear but asks who is the Lord? Thus, Noah demonstrates his total irreverence and unfamiliarity of the scriptures, which state, Thou shalt fear the Lord thy God, and serve him, and shalt swear by his name (Deut 6:13). Noah's faithlessness is reminiscent of Laman and Lemuel who asked, How is it possible that the Lord will deliver Laban into our hands? Behold, he is a mighty man, and he can command fifty, yea, even he can slay fifty; then why not us? (1 Nephi 3:31)
"Such is the dialogue of some of the devil's most distinguished servants. Noah's spirit and words are the same as some of the adversary's most nefarious notables, Cain and Pharaoh, who also challenged the Lord's anointed with the question, 'Who is the Lord?' (Moses 5:16; Exodus 5:2)." (McConkie and Millet, Doctrinal Commentary on the Book of Mormon, vol. 2, p. 204)
