'Fellow citizen' in the Bible

'For this is the covenant that I will make with the house of Israel in those days,' says the Lord; 'I will put my laws into their minds, and write them on their hearts, and I will be their God, and they will be my people. And nevermore will each one need to teach his fellow-citizen,

And they shall not teach each his fellow-citizen, and each his brother, saying, Know the Lord; because all shall know me in themselves, from the little one among them unto the great among them.
