3 Nephi 4:31

And it came to pass that they did break forth, all as one, in singing and praising their God, for the great thing which he had done for them, in preserving them from falling into the hands of their enemies;

They all started singing and praising their God together. They thanked him for the great thing he had done. He had saved them from their enemies.

Then they all burst into song, praising God for the great thing he’d done—for keeping them from falling into their enemies’ hands.
