Augustine of Hippo
Catena Aurea · Johannesevangelium 11
Now a certain man was sick, named Lazarus, of Bethany, the town of Mary and her sister Martha. (It was that Mary which anointed the Lord with ointment, and wiped his feet with her hair, whose brother Lazarus was sick.) Therefore his sisters sent unto him, saying, Lord, behold, he whom thou lovest is sick. When Jesus heard that, he said, This sickness is not unto death, but for the glory of God, that the Son of God might be glorified thereby. Now Jesus loved Martha, and her sister, and Lazarus.
(Tr. xlix. 6) When Jesus heard that, He said, This sickness is not unto death. For this death itself was not unto death, but to give occasion for a miracle; whereby men might be brought to believe in Christ, and so escape real death. It was for the glory of God, wherein observe that our Lord calls Himself God by implication, thus confounding those heretics who say that the Son of God is not God. For the glory of what God? Hear what follows, That the Son of God might be glorified thereby, i. e. by that sickness.
