Parallel
2 Corinthians 4:16
Clementine Vulgate · Berean Standard Bible
Propter quod non deficimus : sed licet is, qui foris est, noster homo corrumpatur, tamen is, qui intus est, renovatur de die in diem.
Therefore we do not lose heart. Though our outer self is wasting away, yet our inner self is being renewed day by day.
