The answer is: Hezekiah

Hezekiah was a king of Judah. 2 Kings 18:14

Hezekiah stands apart in the lineup of kings often associated with Israel, primarily because he ruled over Judah rather than the northern kingdom. The divide between Israel and Judah can cause some confusion since both evolved from the same lineage—descendants of Abraham and, importantly, Jacob, who was also known as Israel. After Solomon's reign, the kingdom split into two factions around 931 BCE: Judah in the south with its capital in Jerusalem and Israel in the north with its capital at Samaria.

What makes Hezekiah notably charismatic is not just his geographical loyalty but also his commitment to religious reform. Think of him as a spiritual innovator; he took radical steps to align his kingdom with worship centered on Yahweh, rejecting idol worship that had permeated that period. In fact, he famously instituted a campaign to purge pagan influences from the temple and reinstituted the Passover celebration (2 Chronicles 30).

The echoes of Hezekiah’s life and leadership resound widely. For instance, it is believed that King Josiah, another strong reformer from Judah, drew inspiration from Hezekiah’s attempts to purify worship. Also, don't overlook Hezekiah's brush with mortality—when faced with illness, it's notable that he converses directly with the prophet Isaiah, asking for a sign to tell him he’ll recover (2 Kings 20). This humanizes biblical royalty, connecting the distant ancient past with universal struggles we all face, such as facing death or striving to lead well.
