His reign marked a period of significant religious reform, as he sought to bring the people back to the worship of the one true God, following the laws given to Moses. This verse indicates that there were additional records, beyond the biblical narrative, that documented his reign and actions. These records, referred to as the annals of the kings of Judah, would have provided detailed accounts of his accomplishments and the changes he implemented.
Josiah's reforms included the removal of idolatrous practices and the restoration of the temple in Jerusalem. He was known for his commitment to the covenant with God, which he renewed with the people. His efforts were aimed at unifying the nation under the worship of Yahweh and eliminating the influences of foreign gods. The mention of these other records suggests that Josiah's impact was significant enough to be recorded in multiple sources, highlighting his importance in the history of Judah and his role in shaping its religious landscape.
