'Neighbor' in the Bible

I said, "So now, you wailing women, hear what the Lord says. Open your ears to the words from his mouth. Teach your daughters this mournful song, and each of you teach your neighbor this lament.

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.
