2 Sam 4:3

4:3 the Beerothites fled to Gittaim. Although Beeroth was one of the four major cities of the Gibeonites (an Amorite people who duped Joshua into making a peace treaty with them; Josh. 9:17), Josh. 18:25 indicates that the town was allotted to Benjamin. King Saul had attempted to annihilate the Gibeonites (21:1, 2), and this aggression may explain the flight of the Beerothites to Gittaim.
