111 Athaliah was the mother of Ahaziah. When she saw that her son was dead, she took over. She began by massacring the entire royal family. 2 But Jehosheba, daughter of King Joram and sister of Ahaziah, took Ahaziah's son Joash and kidnapped him from among the king's sons slated for slaughter. She hid him and his nurse in a private room away from Athaliah. He didn't get killed. 3 He was there with her, hidden away for six years in The Temple of God. Athaliah, oblivious to his existence, ruled the country.

Commentary on 2 Kings 11:1-12
(Read 2 Kings 11:1-12)
Athaliah destroyed all she knew to be akin to the crown. Jehoash, one of the king's sons, was hid. Now was the promise made to David bound up in one life only, and yet it did not fail. Thus to the Son of David, the Lord, according to his promise, will secure a spiritual seed, hidden sometimes, and unseen, but hidden in God's pavilion, and unhurt. Six years Athaliah tyrannized. Then the king was brought forward. A child indeed, but he had a good guardian, and, what was better, a good God to go to With such joy and satisfaction must the kingdom of Christ be welcomed into our hearts, when his throne is set up there, and Satan the usurper is cast out. Say, Let the King, even Jesus, live, for ever live and reign in my soul, and in all the world.
