So you want to know ‘bout Hez’kiah
and you’ve read through the Bible, no d’uh!
If more info you need
you have only to read
the lost Book of the Kings of Judah.
2 Kings 20:20
The Book of the Kings of Judah may be lost, but a bullah (that is, the impression in clay of a royal seal) bearing the name of King Hezekiah has been found.
