Helaman 9:2

Behold, now we will know of a surety, whether this man be a prophet, and God hath commanded him to prophesy such marvellous things unto us. Behold we do not believe that he hath; yea, we do not believe that he is a prophet; nevertheless, if this thing which he hath said concerning the Chief Judge be true, that he be dead, then will we believe that the other words which he hath spoken is true.

“Now we will know for sure whether this man is a prophet and God commanded him to prophesy these amazing things. We don’t believe he is a prophet. But if what he said about the chief judge being dead is true, then we will believe his other words are true.”

“Now we’ll know for sure whether this man is really a prophet—whether God actually commanded him to say these amazing things. We don’t believe he’s a prophet at all. But if what he said about the Chief Judge being dead turns out to be true, then we’ll believe the rest of what he said.”
