Mosiah 15:6

And after all this, and after working many mighty miracles among the children of men, he shall be led, yea, even as Isaiah said, As a sheep before the shearer is dumb, so he opened not his mouth;

After doing many great miracles for people, he will be led away. Isaiah said he would be like a quiet sheep being cut. He won’t speak up.

After all that, after performing incredible miracles, he’ll be led away—just as Isaiah said—like a sheep silent before its shearers. He won’t say a word in his own defense.
