Mosiah 2:6 -2:10

Mosiah 2:6 And they pitched their tents round about the temple, every man having his tent with the door thereof towards the temple, that thereby they might remain in their tents and hear the words which king Benjamin should speak unto them;

They were going to listen in their tents which had been pitched facing the Temple from which king Benjamin was going to speak.
[This is just like General Conference from Salt Lake City. We sit in our homes and listen to the leaders on TV. What a great blessing that is.]

Mosiah 2:7 For the multitude being so great that king Benjamin could not teach them all within the walls of the temple, therefore he caused a tower to be erected, that thereby his people might hear the words which he should speak unto them.

King Benjamin knew that the congregation would be to large for them to all be close enough to hear him speaking. He then had constructed a tower to speak from.
[Wonder if it was a spur of the moment thing of it was planned for and already in place if he did see that the crowd was to large.]

Mosiah 2:8 And it came to pass that he began to speak to his people from the tower; and they could not all hear his words because of the greatness of the multitude; therefore he caused that the words which he spake should be written and sent forth among those that were not under the sound of his voice, that they might also receive his words.

But even that was not enough for all to receive his words. He then directed that his words be written down and distributed to those who could not hear him.

Mosiah 2:9 And these are the words which he spake and caused to be written, saying: My brethren, all ye that have assembled yourselves together, you that can hear my words which I shall speak unto you this day; for I have not commanded you to come up hither to trifle with the words which I shall speak, but that you should hearken unto me, and open your ears that ye may hear, and your hearts that ye may understand, and your minds that the mysteries of God may be unfolded to your view.

Now these are what he spoke to his people which were also record and distributed to those who could not hear him: First king Benjamin says that he had not called this assembly to mints words. He will come straight to the point and speak plainly. In addition, he wants his listeners to pay close attention to what he has to say. He wants their hearts and minds open to his words. He wants them to listen carefully enough to see the depth of what his is trying to reveal to them. If one listens carefully with his heart and mind, he will see insights previously unknown to him.

Mosiah 2:10 I have not commanded you to come up hither that ye should fear me, or that ye should think that I of myself am more than a mortal man.

He does not want anyone to be afraid of him. He is a man like anyone else. His office should not make anyone think that he is better than anyone else. He puts his pants on one leg at a time like the rest of us.
