Isaac, watching through a sizable crack in his door, starts to panic. She obliges, grabbing a butcher's knife from the kitchen and walking to Isaac's room. It states she has done well, but it still questions her devotion, and requests she sacrifice her son. Once more, the voice speaks to Isaac's mother. Once again, his mother obliges, and locks Isaac inside his room. The voice once again speaks to Isaac's mother, stating that Isaac must be cut off from all that is evil in the world. His mother obliges, taking away his toys, drawings, and even his clothes. It asks her to remove all that was evil from Isaac, in an attempt to save him. Isaac's mother then hears 'a voice from above', stating her son is corrupted with sin, and needs to be saved. Isaac, a child, and his mother live in a small house on a hill, both happily keeping to themselves, with Isaac drawing pictures and playing with his toys, and his mother watching Christian broadcasts on television. The Binding of Isaac 's plot is loosely inspired by the biblical story of the same name.
