2 Chronicles 22:10-12

Leeser(i) 10 And when ‘Athalyahu the mother of Achazyahu saw that her son was dead, she arose and exterminated all the royal seed of the house of Judah. 11 But Yehoshab’ath, the daughter of the king, took Joash the son of Achazyahu, and stole him away from the midst of the king’s sons that were slain, and put him and his nurse into the bed-chamber. So did Yehoshab’ath, the daughter of king Jehoram, the wife of Yehoyada’ the priest,—for she was the sister of Achazyahu,—hide him from ‘Athalyahu, so that she slew him not. 12 And he was with them in the house of God hidden six years, while ‘Athalyah was reigning over the land.
