2 Kings 15:2

Sixteen years old was he when he began to reign
By the consent of the people and princes of Judah, ( 2 Kings 14:21 )

and he reigned fifty and two years in Jerusalem:
exclusive of the eleven or twelve years of his minority, from his father's death:

and his mother's name was Jecholiah of Jerusalem;
of whom there is no further account any where.
