4:16 And he selected a wise man who was among the elders of the church, and gave him power according to the voice of the people, that he might have power to enact laws according to the laws which had been given, and to put them in force according to the wickedness and the crimes of the people.

 4:17 Now this man's name was Nephihah, and he was appointed chief judge; and he sat in the judgment-seat to judge and to govern the people.

 4:18 Now Alma did not grant unto him the office of being high priest over the church, but he retained the office of high priest unto himself; but he delivered the judgment-seat unto Nephihah.

 4:19 And this he did that he himself might go forth among his people, or among the people of Nephi, that he might preach the word of God unto them, to stir them up in remembrance of their duty, and that he might pull down, by the word of God, all the pride and craftiness and all the contentions which were among his people, seeing no way that he might reclaim them save it were in bearing down in pure testimony against them.
