Alma 53:20-21

20 And they were all young men, and they were exceedingly valiant for courage, and also for strength and activity; but behold, this was not all—they were men who were true at all times in whatsoever thing they were entrusted.

21 Yea, they were men of truth and soberness, for they had been taught to keep the commandments of God and to walk uprightly before him.
