2 Chronicles 26:3-5 (NLT): "Uzziah was sixteen years old when he became king, and he reigned in Jerusalem fifty-two years. His mother was Jecoliah from Jerusalem. He did what was pleasing in the LORD’s sight, just as his father, Amaziah, had done. Uzziah sought God during the days of Zechariah, who taught him to fear God. And as long as the king sought guidance from the LORD, God gave him success."
2 Chronicles 26:16-21 (NLT): "But when he had become powerful, he also became proud, which led to his downfall. He sinned against the LORD his God by entering the sanctuary of the LORD’s Temple and personally burning incense on the incense altar. Azariah the high priest went in after him with eighty other priests of the LORD, all brave men. They confronted King Uzziah and said, 'It is not for you, Uzziah, to burn incense to the LORD. That is the work of the priests alone, the descendants of Aaron who are set apart for this work. Get out of the sanctuary, for you have sinned. The LORD God will not honor you for this!' Uzziah, who was holding an incense burner, became furious. But as he was standing there raging at the priests before the incense altar in the LORD’s Temple, leprosy suddenly broke out on his forehead. When Azariah the high priest and all the other priests saw the leprosy, they rushed him out. And the king himself was eager to get out because the LORD had struck him. So King Uzziah had leprosy until the day he died. He lived in isolation in a separate house, for he was excluded from the Temple of the LORD. His son Jotham was put in charge of the royal palace, and he governed the people of the land."
Isaiah 6:1–7 (NLT): “It was in the year King Uzziah died that I saw the Lord. He was sitting on a lofty throne, and the train of his robe filled the Temple. 2 Attending him were mighty seraphim, each having six wings. With two wings they covered their faces, with two they covered their feet, and with two they flew. 3 They were calling out to each other, “Holy, holy, holy is the LORD of Heaven’s Armies! The whole earth is filled with his glory!” 4 Their voices shook the Temple to its foundations, and the entire building was filled with smoke. 5 Then I said, “It’s all over! I am doomed, for I am a sinful man. I have filthy lips, and I live among a people with filthy lips. Yet I have seen the King, the LORD of Heaven’s Armies.” 6 Then one of the seraphim flew to me with a burning coal he had taken from the altar with a pair of tongs. 7 He touched my lips with it and said, “See, this coal has touched your lips. Now your guilt is removed, and your sins are forgiven.
