Atos 7:8

8 Então lhe deu a aliança da circuncisão. Assim, Abraão gerou Isaque e o circuncidou no oitavo dia; e Isaque gerou Jacó, e Jacó gerou os doze patriarcas.

8 And he gave him the covenant of circumcision: and so [Abraham] begat Isaac, and circumcised him the eighth day; and Isaac [begat] Jacob, and Jacob the twelve patriarchs.
