3-6. He did that which was right in the sight of the Lord, yet not like David his father—The beginning of his reign was excellent, for he acted the part of a constitutional king, according to the law of God, yet not with perfect sincerity of heart (compare 2Ch 25:2). As in the case of his father Joash, the early promise was belied by the devious course he personally followed in later life (see 2Ch 20:14), as well as by the public irregularities he tolerated in the kingdom.

     5. as soon as the kingdom was confirmed in his hand—It was an act of justice no less than of filial piety to avenge the murder of his father. But it is evident that the two assassins must have possessed considerable weight and influence, as the king was obliged to retain them in his service, and durst not, for fear of their friends and supporters, institute proceedings against them until his power had been fully consolidated.

     6. But the children of the murderers he slew not—This moderation, inspired by the Mosaic law (De 24:16), displays the good character of this prince; for the course thus pursued toward the families of the regicides was directly contrary to the prevailing customs of antiquity, according to which all connected with the criminals were doomed to unsparing destruction.
