3 Nephi 1:25
1830 Edition
But it came to pass that they soon became converted, and were convinced of the error which they were in: for it was made known unto them that the law was not yet fulfilled, and that it must be fulfilled in every whit; yea, the word came unto them that it must be fulfilled; yea, that one jot nor tittle should not pass away, till it should all be fulfilled; therefore in this same year, were they brought to a knowledge of their error, and did confess their faults.

Simple English
But they soon became converted and were convinced of the error they were in, for it was made known to them that the law was not yet fulfilled, and that it must be fulfilled completely. They were told that not one jot or tittle would pass away until it should all be fulfilled. Therefore, in this same year they were brought to a knowledge of their error and confessed their faults.
Paraphrase
Before long though, they came around. They realized their mistake when they learned the law hadn’t been fulfilled yet—it had to be completed entirely. Not one tiny piece could be left undone. That same year they recognized their error and admitted they’d been wrong.
