I Samuel 17:55

55 As Saul watched David going out to meet the Philistine, he said to Abner, commander of the army, "Abner, whose son is that young man?" Abner replied, "As surely as you live, Your Majesty, I don't know."

55 Vendo porém Saul sair Davi a encontrar-se com o filisteu, disse a Abner, o chefe do exército: De quem é filho este mancebo, Abner? E disse Abner: Vive a tua alma, ó rei, que o não sei.
