'Countryman' in the Bible

So I, the Lord, say: "You have not really obeyed me and granted freedom to your neighbor and fellow countryman. Therefore, I will grant you freedom, the freedom to die in war, or by starvation or disease. I, the Lord, affirm it! I will make all the kingdoms of the earth horrified at what happens to you.

"And there will be no need at all for each one to teach his countryman or each one to teach his brother saying, 'Know the Lord,' since they will all know me, from the least to the greatest.
