In this passage about two prophets, who are not named, there are lessons for us on testing those who claim to speak for God by the word of God, and that the word of God always remains true, even when the servants who bear the word of God fail Him.  Other passages mentioned include: 1 Peter 2:11; Philippians 3:20; Hebrews 13:14; Matthew 7:15; 1 John 4:1
