Alma 43

"And thus having placed his army according to his desire, he was prepared to meet them" (Alma 43:33).

Captain Moroni prepared his military force with armor. After counseling with the prophet, he placed his main portion of his army where it was going to be needed.

Hugh Nibley said:

“The Lamanite campaign was directed by Amalekite and Zoramite officers, whose knowledge of Nephite military secrets and methods would have given them an enormous advantage over any commander but Moroni. Right at the outset his foresight had robbed them of their first and logical objective—the buffer land of Jershon (Alma 43:22). He had taken up his main defensive position there, but when the messengers returned from consulting the prophet he learned that the Lamanites were planning a surprise by directing their push against the more inaccessible but weaker land of Manti, where they would not be expected (Alma 43:24). Immediately Moroni moved his main army into Manti and put the people there in a state of preparedness (Alma 43:25–26).
“Informed of every Lamanite move by his spies and scouts, Moroni was able to lay a trap for the enemy, catching them off-guard as they were fording the river Sidon (Alma 43:28–35)” (Since Cumorah, 297–98).

We should prepare in our lives. Prepare by turning to the prophets and following their counsel. General Conference is coming up. It is a great opportunity to listen to the words and counsel of the prophets and listen to the Spirit for inspiration for the best way to be obedient.
