Igitur Joab et Abisai frater ejus interfecerunt Abner, eo quod occidisset Asaël fratrem eorum in Gabaon in prælio.
So Joab and Abisai his brother slew Abner, because he had killed their brother Asael at Gabaon in the battle.
Ergo Ioabe et Abisao fratre de illo interfice Abnro, eo quod occide Asaële fratre de illos in Gabaone in praelio.
