You must set apart ¹  for the Lord your God every firstborn male born to your herds and flocks. You must not work the firstborn of your bulls or shear the firstborn of your flocks.

Your ox will be slaughtered before your very eyes but you will not eat of it. Your donkey will be stolen from you as you watch and will not be returned to you. Your flock of sheep will be given to your enemies and there will be no one to save you.
