C. F. Keil and Franz Delitzsch on 1 Kings 2:23-24

1Ki 2:23-24

Solomon thereupon solemnly swore (the formula of an oath, and the כּי introducing the oath, as in 1Sa 14:44, etc.), “Adonijah has spoken this word against his own life.” בּנפשׁו, at the cost of his life, as in 2Sa 23:17, i.e., at the hazard of his life, or to his destruction. 2Sa 23:24. “And now, as truly as Jehovah liveth, who hath established me and set me on the throne of my father David, and hath made me a house, as He said (verbatim, 2Sa 7:11): yea, to-day shall Adonijah be put to death.” Jehovah established Solomon, or founded him firmly, by raising him to the throne in spite of Adonijah’s usurpation. In ויושׁיביני the central י has got into the text through a copyist’s error. בּית לי עשׂה, i.e., He has bestowed upon me a family or posterity. Solomon had already one son, viz., Rehoboam, about a year old (compare 1Ki 11:42 with 1Ki 14:21 and 2Ch 12:13).When Thenius denies this, and maintains that Rehoboam cannot have been 41 years old when he began to reign, referring to his discussion at 1Ki 14:21, he answers himself, inasmuch as at 1Ki 14:21 he demonstrates the fallacy of the objections which Cappellus has raised against the correctness of the reading “41 years.”
