3 Nephi 4:10

but in this thing they were disappointed, for the Nephites did not fear them, but they did fear their God, and did supplicate him for protection; therefore when the armies of Giddianhi did rush upon them, they were prepared to meet them; yea, in the strength of the Lord they did receive them;

But they were wrong. The Nephites were not scared of them. They were only scared of God. They asked him to protect them. So when Giddianhi’s armies rushed at them, they were ready. They fought in the Lord’s strength.

But they were wrong. The Nephites weren’t afraid of them—they feared only God. They were praying for his protection. So when Giddianhi’s armies rushed at them, the Nephites were ready. They stood strong in the Lord’s strength and met the attack.
