10 “And the Lord has become a refuge to the poor”. Whatsoever be the persecutions of that enemy, who has been turned behind, what harm shall he do to them whose refuge the Lord has become? But this will be, if in this world, in which that one has an office of power, they shall choose to be poor, by loving nothing which either here leaves a man while he lives and loves, or is left by him when he dies. For to such a poor man has the Lord become a refuge, “an Helper in due season, in tribulation.” Lo, He makes poor, for “He scourges every son whom He receives.” For what “an Helper in due season” is, he explained by adding “in tribulation.” For the soul is not turned to God, save when it is turned away from this world: nor is it more seasonably turned away from this world, except toils and pains be mingled with its trifling and hurtful and destructive pleasures.
