because You will not abandon my soul to Hades, nor will You let Your Holy One see decay.
Because thou wilt not leave my soul in hell, neither wilt thou suffer thine Holy One to see corruption. (t) You will not allow me to remain in the grave.
The Hebrew words for soul and grave both belong to death's vocabulary, Sheol because death never satisfies its hunger, Shachat because it means corruption itself. Peter is not laboring to prove Christ descended into hell; that disputes what the prophet never meant to establish. Soul here signifies life itself, not some immortal essence floating separate. What matters is that God would not leave His Holy One abandoned to the grave's dominion.
