[259] When the high priest had spoken thus, he did not persuade Saul, his fear was so prevalent, that he could not give credit to an apology that was very just. So he commanded his armed men that stood about him to kill him, and all his kindred; but as they durst not touch the high priest, but were more afraid of disobeying God than the king, he ordered Doeg the Syrian to kill them. Accordingly, he took to his assistance such wicked men as were like himself, and slew Ahimelech and all his family, who were in all three hundred and eighty-five. Saul also sent to Nob, ¹ the city of the priests, and slew all that were there, without sparing either women or children, or any other age, and burnt it; only there was one son of Ahimelech, whose name was Abiathar, who escaped. However, these things came to pass as God had foretold to Eli the high priest, when he said that his posterity should be destroyed, on account of the transgression of his two sons.
