In the biblical context, the concept of the "neighbor" is deeply rooted in the social and religious fabric of ancient Israelite society. The Hebrew word for neighbor, "רֵעַ" (rea), appears frequently in the Old Testament and carries significant theological and ethical implications. The treatment of one's neighbor is a central theme in the Hebrew Scriptures, reflecting God's covenantal expectations for His people.

Old Testament Context

The idea of the neighbor is first introduced in the Pentateuch, where it is closely associated with the covenantal laws given to the Israelites. In Leviticus 19:18, the commandment to "love your neighbor as yourself" is presented as a fundamental principle of the Law: "Do not seek revenge or bear a grudge against any of your people, but love your neighbor as yourself. I am the LORD" . This commandment is part of the Holiness Code, which outlines the ethical and moral conduct expected of God's chosen people.

The treatment of neighbors is further elaborated in the Ten Commandments, where several commandments directly address interpersonal relationships. For instance, Exodus 20:16-17 warns against bearing false witness and coveting a neighbor's possessions: "You shall not give false testimony against your neighbor. You shall not covet your neighbor’s house. You shall not covet your neighbor’s wife, or his manservant or maidservant, his ox or donkey, or anything that belongs to your neighbor" . These commandments underscore the importance of honesty, integrity, and respect for others' property and relationships.

Prophetic Literature

The prophetic books often address the treatment of neighbors as a reflection of Israel's faithfulness to God. The prophets frequently rebuke the Israelites for social injustices and call them to repentance. For example, in Jeremiah 22:13, the prophet condemns those who exploit their neighbors: "Woe to him who builds his house by unrighteousness and his upper rooms by injustice, who makes his neighbor serve him for nothing and does not give him his wages" . This highlights the expectation of justice and fairness in dealings with others.

Wisdom Literature

The wisdom literature of the Old Testament also provides insights into the concept of the neighbor. Proverbs 3:28 advises, "Do not say to your neighbor, 'Come back tomorrow and I will provide'—when you already have the means" . This proverb emphasizes the importance of generosity and timely assistance, reflecting a broader ethic of care and responsibility towards one's community.

New Testament Fulfillment

In the New Testament, Jesus Christ reaffirms and expands upon the Old Testament teachings regarding neighbors. In the parable of the Good Samaritan (Luke 10:25-37), Jesus illustrates that the definition of "neighbor" transcends ethnic and social boundaries. When asked, "And who is my neighbor?" (Luke 10:29), Jesus responds with a account that challenges prevailing prejudices and calls for compassion and mercy towards all people, regardless of their background.

Jesus' teaching in Matthew 22:37-39 further elevates the commandment to love one's neighbor, placing it alongside the greatest commandment to love God: "Jesus declared, 'Love the Lord your God with all your heart and with all your soul and with all your mind.' This is the first and greatest commandment. And the second is like it: 'Love your neighbor as yourself'" . This dual commandment encapsulates the essence of the Law and the Prophets, emphasizing the inseparable link between love for God and love for others.

Theological Implications

The biblical concept of the neighbor is not merely a social or ethical guideline but is deeply theological, reflecting God's character and His desire for a just and compassionate community. The call to love one's neighbor is a reflection of God's love for humanity and His covenantal relationship with His people. It challenges believers to embody God's love in their interactions with others, promoting a society marked by justice, mercy, and mutual respect.
