2:3 written in the law of Moses. It is evident that the Israelites had access to the Pentateuch at this time, contrary to the speculations of critics who allege that these documents date from a much later period. Note also Nehemiah 8:1.

2:5 what Joab. Joab had not only collaborated in the conspiracy of Adonijah, but had also used treachery in murdering Abner and Amasa (I Kings 1:7; II Samuel 3:27; 20:10), as well as killing Absalom (II Samuel 18:14)

2:7 sons of Barzillai. Despite his advanced age, Barzillai had provided much assistance to David when he had to flee Jerusalem when Absalom rebelled (II Samuel 19:33-39). On the other hand, Shimei had opposed and cursed David at this same time (II Samuel 16:5-13; 19:16). In I Kings 2:8,9, David adjured Solomon to take vengeance on Shimei.

2:10 in the city of David. The supposed tomb of David is a prominent landmark in modern Jerusalem, located on Mount Zion.

2:17 Abishag the Shunammite. This request was a gratuitous insult from Adonijah to his younger brother Solomon, in effect assuming the role of “brother” to his own father. Abishag was David’s last wife before he died, and had no children, so Adonijah would thus be arrogating that role to himself. Even if this were not a part of his thinking, such a relationship would clearly be an incestuous violation of the divine law (Leviticus 18:6-8,29), subject to capital punishment.

2:21 given to Adonijah. Bathsheba was somehow persuaded by Adonijah to request of Solomon that Abishag, David’s wife, be given to him in marriage. This would be tantamount to claiming David’s throne, and it would seem that Bathsheba would realize this. Perhaps this was the reason she agreed, knowing that such a request would almost inevitably be used as a justification for Solomon to order Adonijah’s execution.

2:27 which he spake. This prophecy (I Samuel 2:31-35) had been given over a century earlier. Abiathar was the last of the family of Eli to serve in the priesthood.

2:29 by the altar. See note on I Kings 1:50.
