2 Kings 11:19-23

And he took the captains of hundreds and the Carites, and the guards and all the people of the land; and they brought the king down from the house of the Lord, and came by way of the gate of the guards to the king’s house. And he sat on the throne of the kings.

So all the people of the land rejoiced and the city was peaceful. For they had put Athaliah to death with the sword at the king’s house.

Jehoash was seven years old when he became king.
