Hippolytus of Rome — on Gal 1:1 (Hippolytus Dogmatical and Historical Fragments)

“And the expression, "he stooped down, he couched as a lion, and as a lion's whelp," refers to the three days' sleep (death, couching) of Christ; as also Isaiah says, "How is faithful Sion become an harlot! it was full of judgment; in which righteousness lodged (couched); but now murderers." And David says to the same effect, "I laid me down (couched) and slept; I awaked: for the Lord will sustain me;" in which words he points to the fact of his sleep and rising again. And Jacob says, "Who shall rouse him up?" And that is just what David and Paul both refer to, as when Paul says, "and God the Father, who raised Him from the dead."”
