Helaman 5:13

And it came to pass that these were the words which Helaman taught to his sons; yea, he did teach them many things which are not written, and also many things which are written.

These were the words Helaman taught his sons. He taught them many things that are not written. He also taught many things that are written.

These were the words Helaman taught his sons. He taught them many other things too—some that were written down and some that weren’t.
