3 Nephi 26:14

And it came to pass that he did teach and minister unto the children of the multitude of whom hath been spoken, and he did loose their tongues, and they did speak unto their fathers great and marvellous things, even greater than he had revealed unto the people, and loosed their tongues that they could utter.

He taught and helped the children of the crowd I told you about. He helped them speak. They spoke amazing things to their fathers. What they said was even greater than what Jesus had told the people. He helped them speak so they could say these things.

He taught and ministered to the children in the crowd. He freed their tongues, and they spoke to their parents about great and marvelous things—even more amazing than what he had revealed to the adults. He gave them the ability to express things they couldn’t before.
