Two Treatises on Government/needy
From Critiques Of Libertarianism
But we know God hath not left one man so to the mercy of another, that he may starve him if he please: God the Lord and Father of all has given no one of his children such a property in his peculiar portion of the things of this world, but that he has given his needy brother a right to the surplusage of his goods; so that it cannot justly be denied him, when his pressing wants call for it: and therefore no man could ever have a just power over the life of another by right of property in land or possessions; since it would always be a sin, in any man of estate, to let his brother perish for want of affording him relief out of his plenty.
John Locke, "Two Treatises on Government, Chapter 4, §. 42."
