Éxodo 4

And I say to you, Let My son go, that he may serve Me. And if you refuse to let him go, behold, I am going to kill your son, your first-born.

Ya te he dicho que dejes ir á mi hijo, para que me sirva, mas no has querido dejarlo ir: he aquí yo voy á matar á tu hijo, tu primogénito.

And I say unto thee, Let my son go, that he may serve me: and if thou refuse to let him go, behold, I will slay thy son, even thy firstborn.

and I have said to you, “Let my son go, that he may serve me;” and you have refused to let him go. Behold, I will kill your firstborn son.’”
