I have been a stranger in a strange land.
Learn not the way of the heathen.
Thou shalt love him as thy self.
Thou shalt neither vex a stranger, nor oppress him: for ye were strangers in the land of Egypt.
Unto a stranger thou mayest lend upon usury; but unto thy brother thou shalt not lend upon usury.
The character of a people may be ruined by charity.
