Mosiah 12:11 - 12:15

Mosiah 12:11 And again, he saith that thou shalt be as a stalk, even as a dry stalk of the field, which is run over by the beasts and trodden under foot.

Or like a harvested wheat stalk that is walked on because it is of no value.

Mosiah 12:12 And again, he saith thou shalt be as the blossoms of a thistle, which, when it is fully ripe, if the wind bloweth, it is driven forth upon the face of the land. And he pretendeth the Lord hath spoken it. And he saith all this shall come upon thee except thou repent, and this because of thine iniquities.

Or like the blossoms of a thistle that when it is ripe and the wind blows, it is scattered over the land. All these things Abinadi said came from the Lord by revelation. However, they knew that Abinadi was only making this all up and that the Lord never spoke to him saying that the king must repent or suffer the before mentioned fate.

Mosiah 12:13 And now, O king, what great evil hast thou done, or what great sins have thy people committed, that we should be condemned of God or judged of this man?

Now the accusers now asked rhetorically what had the king done to be told that such a fate awaited him if he did not repent? In fact why were the people themselves also accused of such behavior.

Mosiah 12:14 And now, O king, behold, we are guiltless, and thou, O king, hast not sinned; therefore, this man has lied concerning you, and he has prophesied in vain.

The accusers now tell the king that neither we or the king are guilty of nothing that could be construed as evil or wicked. The man is delusional and his words are of a lunatic.
[This is an effort by the accusers to play down what Abinadi is saying because it threatened their cushy jobs and positions. If what he accused them of was true, they would lose the tax money and would have to go to work for a living. And I am sure some of them wanted to silence Abinadi because he was pricking their consciences.]

Mosiah 12:15 And behold, we are strong, we shall not come into bondage, or be taken captive by our enemies; yea, and thou hast prospered in the land, and thou shalt also prosper.

The accusers tell the king that they are a strong people and no one would overcome them and the proof is their prosperity and the good life they lead.
