Éxodo 4

Therefore I say unto thee, Let my son go, that he may serve me, But if thou refuse to let him go, behold, I, am going to slay, thy son, thy firstborn.

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.’”
