Matthew Poole's Concise Commentary
1 Kings 2:22
Ask for him the kingdom also: his design is not upon Abishag, but upon the kingdom; which, by this means, he thinks to recover; partly because she was the last king's wife, or concubine, which might strengthen his pretence to the crown; see 2 Samuel 3:7, 2 Samuel 12:8 16:21; and partly because by her eminent beauty, and near relation to David, she had a powerful interest in the court. Quest. Was not this too harsh a censure, and the following punishment of it too severe? Answ.
1. That Adonijah had such a design is very probable, both from his temper, for he was an aspiring and designing man, and highly discontented with Solomon's government, and desirous of a change; and from the nature of the thing, because he would not have made so daring and presumptuous a request, if he had not some great design in it.
2. It is very likely from the following words, though not expressed, that he, and Joab, and Abiathar were engaged in some design against Solomon, and that Solomon had got information of it; and therefore he did and might reasonably take this for an indication, and the first overt act of his treason.
3. Solomon did not pardon Adonijah's treason simply and absolutely, but upon condition that he carried himself worthily, 1 Kings 1:52; and this being confessedly a bold and unworthy action, and arguing more confidence and presumption than became him, and carrying in it the appearance and intention of an incestuous marriage, he might justly revive his guilt, and take this occasion to execute the sentence which he formerly deserved. If it be said, That it is very improbable that Adonijah should expect to get the kingdom from Solomon, who was so firmly established in it with universal applause; it may be answered, That Adonijah was not the only man that hath fed himself with vain hopes, and engaged himself in high and treasonable designs, where to other wise men there was but little likelihood of success; and that he might now be only laying the foundation of what he further intended, when he saw a fit time, and getting a pretence for his future attempts upon the crown; either when Solomon should lose the people's affections, as David had done; or when Solomon should die, which also Adonijah might secretly procure and hasten; and he had only Solomon's young and tender son to contest with. All which, and many other things, Solomon in his great wisdom might easily discern; yea, or have some secret intelligence of, though it be not recorded. He is mine elder brother; he looks upon the kingdom as his by nature and birthright, and the law of nations; and therefore he may seek to recover his own, and to cast me out as a usurper. And for Abiathar and for Joab; who have all a hand in the plot, though he alone appear in it; which appears the more likely, because of Solomon proceeding against them all at the same time, as appears in the following verses.
