Mosiah 11:11 - 11:15
Mosiah 11:11 And the seats which were set apart for the high priests, which were above all the other seats, he did ornament with pure gold; and he caused a breastwork to be built before them, that they might rest their bodies and their arms upon while they should speak lying and vain words to his people.
In the place occupied by his priests, he had their seats elevated above the others in the auditorium so they could preach false doctrine and the people would have to look up to them as they did so.
Mosiah 11:12 And it came to pass that he built a tower near the temple; yea, a very high tower, even so high that he could stand upon the top thereof and overlook the land of Shilom, and also the land of Shemlon, which was possessed by the Lamanites; and he could even look over all the land round about.
A high tower was built near the Temple so his forces could overlook the neighboring city of Shilom and also the land of Shemlon where the Lamanites lived. He had a clear view of all of the countryside.
Mosiah 11:13 And it came to pass that he caused many buildings to be built in the land Shilom; and he caused a great tower to be built on the hill north of the land Shilom, which had been a resort for the children of Nephi at the time they fled out of the land; and thus he did do with the riches which he obtained by the taxation of his people.
In addition, king Noah constructed many buildings in Shilom and a large tower on a hill north of the town. This hill had been a place of refused for the Nephi and his followers when they had to flee from the murderous attempts of Laman and Lemuel. All these building projects were funded by the heavy taxation of the king.
Mosiah 11:14 And it came to pass that he placed his heart upon his riches, and he spent his time in riotous living with his wives and his concubines; and so did also his priests spend their time with harlots.
He became obsessed with the riches he was accumulating and spent his time in high living with all his girlfriends as did his handpicked priests.
Mosiah 11:15 And it came to pass that he planted vineyards round about in the land; and he built wine-presses, and made wine in abundance; and therefore he became a wine-bibber, and also his people.
He also had many vineyards round about which produced large amounts of wine which was freely indulged in by both the king, his priests and the people themselves.
