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.

 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.
