2 Kings 11:11-2 Kings 12:3 - Joash Becomes King
11 And the guard stood every man with his weapon in his hand round about the king, from the right corner of the temple to the left along by the altar and the temple.
12 And he brought out the son of the king and put the crown upon him, and delivered him the witness, and made him king and anointed him. And they clapped their hands and said, "God save the king."
13 And when Athaliah heard the noise of the running of the people, she came to the people into the house of the LORD. 14 And when she saw the king stand by a pillar - as the manner was - and the singers and the trumpets by the king, and all the people of the land rejoicing, and the blowing of the trumpets, she rent her clothes and cried, "Treason! Treason!"
15 And Jehoiada the priest commanded the captains of the hundreds that had the rule of the host, and said to them, "Bring her without the wall. And if any follow her, let him die with the sword. For the priest said, "She may not be slain in the house of the LORD." 16 And they laid hands on her, and she went the way that the horses of the kings went out and was slain there.
17 And Jehoiada made a covenant both between the LORD and the king, and between the people and the LORD, that they should be the LORD's people: and also between the king and the people. 18 Then all the people of the land went into the house of Baal, and destroyed his altars, and brake down his images lustily, and slew Nathan, the priest of Baal, before the altar. And the priest set watchmen in the house of the LORD, 19 and took the rulers over hundreds and the captains and the guard and all the people of the land. And they brought the king from the house of the LORD and went the way of the gate of the guard of the king's house. And he sat him down on the seat of the kings. 20 And all the people of the land rejoiced, and the city was in quiet. And they slew Athaliah with the sword in the house of the king.
21 Jehoash was seven years old when he was made king.
1 And he began to reign the seventh year of Jehu, and reigned forty years in Jerusalem. His mother's name was Zibiah of Beersheba. 2 And he did that pleased the LORD, as long as Jehoiada the Priest informed him. 3 But they took not away the hill altars, for the people slew and offered still in the hill altars.
