Shachath (שַׁחַת) refers to a pit, grave, or place of destruction — often used as a poetic image for death, Sheol, and moral corruption. Appearing over 20 times, it carries a dual sense: the literal pit one might fall into and the spiritual abyss of ruin. It is closely connected to words for decay and corruption, making it a powerful image of death's domain.
Theologically, shachath represents the fate of the wicked — the pit of destruction from which God rescues the righteous. The Psalms frequently contrast the righteous, who are delivered from the pit, with the wicked who fall into it. Its most significant theological use appears in Psalm 16:10, quoted in Acts 2 and 13 as pointing to the resurrection of Christ, whose body would not see shachath (corruption).
The messianic import of shachath is immense. When Peter quotes Psalm 16:10 in Acts 2:27 — 'you will not let your holy one see decay' — he applies it directly to Jesus' resurrection. David's body did see corruption; Jesus' did not. The word thus becomes a resurrection promise embedded in the Psalter. The pit that claims all flesh could not hold the Son of God.
