Helaman 9:5

but now when they saw they believed, and fear came upon them, lest all the judgements which Nephi had spoken should come upon the people; therefore they did quake, and had fallen to the earth.

But now when they saw it, they believed. Fear came upon them that all the judgments Nephi had spoken would come upon the people. They trembled and fell to the ground.

But now that they saw it with their own eyes, they believed—and fear gripped them. What if everything else Nephi said was about to come true? They trembled and fell to the ground.
