The director's intial cut was much longer than the version that eventually made it to theaters and video. Amongst the missing footage:
A longer prologue where several other adults are killed, most noticlbly a deputy whose throat is slashed and then stabbed in the chest, and a farmer who is hacked to death outside his barn by a group of pick-axe wielding kids.
A scene between Sarah and Job's parents before the slaughter. They talk over the breakfast table about Sarah's drawings of the upcoming massacre and how they think something awful is about to happen. A scene where Isaac prays to He Who Walks Behind The Rows only to receive a horrific vision of his impending fate
