2 Samuel 4:2

And Saul's son had two men [that were] captains of bands
Of troops in the army, or of guards about the person of Ishbosheth son of Saul:

the name of the one [was] Baanah, and the name of the other Rechab, the
sons of Rimmon a Beerothite, of the children of Benjamin;
so that these men were brethren in nature, as well as in iniquity; they had the same father, who is described by his name and city, and their names are expressly mentioned and recorded to their infamy; and they were not only the servants of Ishbosheth, who had commissions under him, but were of the same tribe with him; all which is observed as an aggravation of their crime:

for Beeroth also was reckoned to Benjamin;
the place from whom Rimmon their father is denominated, and where he dwelt, as well as Gittaim, where they had sojourned, as in ( 2 Samuel 4:3 ) . This place, Beeroth, originally belonged to the Gibeonites, and fell to the lot of Benjamin at the division of the land, see ( Joshua 9:17 ) ( 18:25 ) .
