'Neighbor' in the Bible

Therefore, this is what the LORD says: "I'm about to put stumbling blocks in front of this people, and fathers and sons will stumble over them together. The neighbor and his friends will perish."

but rather, truly change your ways and your deeds. If you truly practice justice between each person and his neighbor,

"How terrible for him who builds his house without righteousness, and its upper rooms without justice, who makes his neighbor work for nothing, and does not pay him his wage.

No longer will a person teach his neighbor or his relative: "Know the LORD.' Instead, they'll all know me, from the least to the greatest of them," declares the LORD. "Indeed, I'll forgive their iniquity, and I'll remember their sin no more."
