Verses 1-9
K. Jotham ch27
Jotham was also a good king. He built up the temple and so contributed to the greater glory of Yahweh ( 2 Chronicles 27:3). Consequently his neighbors to the east submitted to him and paid him tribute ( 2 Chronicles 27:5). The Chronicler clearly stated the reason Jotham became strong: "he ordered his ways [i.e, conducted himself] before the LORD his God" ( 2 Chronicles 27:6).
However, Jotham appears to have failed to lead his people in righteousness ( 2 Chronicles 27:2). There was no reformation of abuses or revival during his reign, as far as we know.
Evidently the reference to Jotham not entering the temple ( 2 Chronicles 27:2) means that he did not inappropriately violate the holy place as his father had done ( 2 Chronicles 26:16).
