Gregory the Great — on Job 5:15 (Morals on the Book of Job, Book VI)

“MORAL INTERPRETATION. But he shall save the poor from the sword of their mouth, and from the hand of the mighty. For the 'poor' is everyone that is not set up in his own eyes. And hence 'Truth' saith in the Gospel, Blessed are the poor in spirit, for theirs is the kingdom of heaven. Now a person is drawn into sin in two ways. For either he is led on by pleasure, or overcome by fear. For 'the sword of the mouth' is the mischievousness of persuasion, but 'the hand of the mighty' is the opposition of power. But because he that is truly humble, who is here called 'the poor,' as he covets none of the good things of this world, so also undauntedly sets at nought even its adverse fortune, it is well said, But He saveth the poor from the sword of their mouth, and from the hand of the mighty. As if it were put plainly; 'God doth so firmly establish the souls of the humble in Himself, that neither the alluring arts of persuasion can draw them, nor the pains of punishment break them in to the practice of sin. For hope rears the spirit into the eternal world, and therefore it is not sensible of any of the ills without, that it falls under.”
