Theophylact of Ohrid — as excerpted in the Catena Aurea on Luke 17:5-6

“The disciples hearing our Lord discoursing of certain arduous duties, such as poverty, and avoiding offences, entreat Him to increase their faith, that so they might be able to follow poverty, (for nothing so prompts to a life of poverty as faith and hope in the Lord,) and through faith to guard against giving offences. Therefore it is said, And the Apostles said unto the Lord, Increase our faith.”
