Charles Ellicott Commentary 2 Samuel 16:5

"And when king David came to Bahurim, behold, there came out thence a man of the family of the house of Saul, whose name was Shimei, the son of Gera; he came out, and cursed still as he came." — 2 Samuel 16:5 (ASV)

Bahurim. —See Note on 2 Samuel 3:16.

Of the family of the house of Saul. —That is, “of the family,” in the larger sense of tribe. Many of the Benjamites naturally felt aggrieved when the royal house passed away from their tribe; and, although under restraint while David’s government was strong, were ever ready to show their opposition and hatred when opportunity offered, as now with Shimei, and a little later with Sheba, the son of Bichri (2 Samuel 20:1–2).
