Éxodo 12

and it hath come to pass when your sons say unto you, What †is this service ye have?

Y cuando os dijeren vuestros hijos: ¿Qué rito es este vuestro?

And it shall come to pass, when your children shall say unto you, What mean ye by this service?

It will happen, when your children ask you, ‘What do you mean by this service?’
