Every Passover lamb, every burnt offering, every peace offering required shachat. The word permeates Exodus, Leviticus, and Numbers as the act that makes atonement possible. Isaiah 53:7 describes the suffering servant as a lamb led to slaughter — using imagery built on centuries of levitical shachat. The New Testament reveals Jesus as the ultimate fulfillment: the Lamb slaughtered once for all (Revelation 5:6, 12).
Shachat is the technical term for ritual slaughter — the killing of animals for sacrifice, food, or judgment. It is distinct from general killing (harag, muwt) in its sacrificial precision, and appears throughout the levitical and priestly legislation.
