Eastern Fathers
Gregory of Nyssa
Yea, the prophet David also, according to the interpretation of the great Peter, said with foresight of Him, "Thou wilt not leave My soul in hell, neither wilt Thou suffer Thine Holy One to see corruption," while the Apostle Peter thus expounds the saying, that "His soul was not left in hell, neither His flesh did see corruption."
