Notes on the Bible, by Albert Barnes, [1834], at sacred-texts.com
2 Kings (2 Samuel) Chapter 16
A couple of donkeys saddled - Those that Mephibosheth and his servant should have ridden. See Sa2 19:26 note.
Thy master's son - Meaning Saul's grandson Sa2 9:6. David asks the question, evidently hurt at the apparent ingratitude of Mephibosheth. It is impossible to say whether Mephibosheth was quite guiltless or not. If Ps. 116 was composed by David, and after the quelling of Absalom's rebellion, Sa2 16:11 may contain David's confession of his present hasty judgment Sa2 16:4 in the matter.
Bahurim - See Sa2 3:16 note. It seems to have lain off the road, on a ridge Sa2 16:13, separated from it by a narrow ravine, so that Shimei was out of easy reach though within hearing, and within a stone's throw Sa2 16:6, Sa2 16:9.
Shimei, the son of Gera - In the title to Ps. 7 he is apparently called "Cush the Benjamite." On Gera, see Jdg 3:15 note.
Come out - Rather, "Go out," namely, of the land, into banishment. Compare Jer 29:16.
Thou bloody man - See the margin. The Lord's word to David Ch1 22:8 was probably known to Shimei and now cast in David's teeth by him, with special reference to the innocent blood of Uriah.
All the blood of the house of Saul - Shimei probably put to David's account the death of Saul, and Jonathan, and Abinadab, and Melchishua, slain in battle by the Philistines with whom David was in league; of Ish-bosheth, slain in consequence of David's league with Abner; that of Abner himself, which he attributed to David's secret orders; and all the 360 slain in the battle between Joab and Abner Sa2 2:31. Some, too, think that the death of seven men of Saul's immediate family Sa2 21:8 had occurred before David's flight, and was referred to by Shimei. Shimei's hatred and virulence is an indication that the Benjamites resented the loss of royalty in their tribe, even in the palmiest days of David's monarchy.
This dead dog - See the marginal reference and Sa2 9:8 note.
Go over - The ravine, possibly with a stream of water Sa2 17:20, which lay between them and Shimei.
What have I to do ... - See the marginal references compare Mat 8:29; Joh 2:4, and a similar complaint about the sons of Zeruiah Sa2 3:39. And for a like striking incident in the life of the Son of David, see Luk 9:52-56.
His cursing - Another reading has "my curse," i. e., the curse that has fallen upon me. David recognizes in every word and action that he was receiving the due reward of his sin, and that which Nathan had foretold.
Taking possession of the harem was the most decided act of sovereignty (see Kg1 2:22). It was also the greatest offence and insult that could be offered. Such an act on Absalom's part made reconciliation impossible. A further motive has been found in this advice, namely, the desire on the part of Ahithophel to make David taste the bitterness of that cup which he had caused others (Uriah and all Bath-sheba's family) to drink, and receive the measure which he had meted withal.
