Mosiah 9:17

"Yea, in the strength of the Lord did we go forth to battle against the Lamanites..."

King Zeniff recounts how his people came to live in the Land of Lehi-Nephi.  He realizes that the Lamanites let them live there because the Lamanites hated them and wanted to destroy them.  After 12 years, King Zeniff realizes this and prepares to battle.  He and his people prayed to God and received strength.  They were able to overcome their enemies because the Lord was on their side.  If you have the Lord with you, you can do anything!
