Verse 23. - And the rest of the sets of Joram, and all that he did, are they not written in the book of the chronicles of the kings of Judah? Some of these acts are recorded in our present Second Book of Chronicles; e.g. his execution of his brothers and of many nobles (2 Chronicles 21:4); his erection of high places (2 Chronicles 21:11); his persecution of the followers of Jehovah (2 Chronicles 21:11); his reception of a writing from Elisha, which, however, had no effect upon his conduct (2 Chronicles 21:12-15); his war with the Philistines (2 Chronicles 21:16) and with the Arabs (2 Chronicles 21:16); his loss of all his sons but one during his lifetime; his long illness, and his painful death (2 Chronicles 21:18, 19). But the 'Book of the Chronicles of the Kings of Judah' was a work on a larger scale than the extant Book of Chronicles, and probably went into much greater detail.
8:16-24 A general idea is given of Jehoram's badness. His father, no doubt, had him taught the true knowledge of the Lord, but did ill to marry him to the daughter of Ahab; no good could come of union with an idolatrous family.
And the rest of the acts of Joram, and all that he did, are they not written in the book of the chronicles of the kings of Judah? Not in the canonical book of Chronicles, though some of his acts are recorded there, see 2 Chronicles 21:1 but in the annals of the kings of Judah, written by persons appointed for that purpose.
