Deuteronomio 7:9

Conoce, pues, que Jehová tu Dios es Dios, Dios fiel, que guarda el pacto y la misericordia á los que le aman y guardan sus mandamientos, hasta las mil generaciones;

Know therefore that the LORD thy God, he is God, the faithful God, which keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations;
