Leviticus 19:18 ('love your neighbor as yourself') defines 'neighbor' narrowly as a fellow Israelite, exposing the command as ethnocentric tribal ethics rather than a universal moral principle.

The claim that Lev 19:18 is exclusively intra-ethnic requires ignoring the immediate literary context of the very same chapter, which is decisive counter-evidence, not a later reinterpretation. Sixteen verses later, in the same chapter and the same legal unit, Lev 19:33-34 states: 'When an alien resides with you in your land, you shall not oppress the alien. The alien who resides with you shall be to you as the citizen among you; you shall love the alien as yourself, for you were aliens in the land of Egypt.' This is the identical verb (*ve-ahavta*, 'and you shall love') and the identical formula ('as yourself') applied explicitly and deliberately to the *ger* — the resident non-Israelite foreigner — grounded in Israel's own experience of being oppressed foreigners in Egypt. The chapter is not silent on scope; it addresses scope directly and extends the command. Historical-critical honesty requires conceding that *reʿa*'s primary referent in v.18 is most naturally the covenant community (Jacob Milgrom, Jon Levenson, and others read it this way as the base sense) — this is a real feature of the text's original social horizon, and universalist readings should not pretend otherwise. But 'primarily addressed to' is not 'restricted to,' and the same textual unit's explicit extension to the *ger* shows the principle was already understood by its own author(s) as extendable beyond ethnic kinship, on the theological ground of shared human vulnerability and God's own action in the Exodus, not tribal loyalty. Jesus's engagement with this exact question in Luke 10:25-37 (the parable of the Good Samaritan, prompted by a lawyer asking 'who is my neighbor?') is not an innovation imposed on a closed text but a first-century rabbinic-style halakhic argument extending a boundary question the text itself had already opened, using a hated ethnic and religious out-group (Samaritans) as the parable's hero specifically to press the logic of Lev 19:34 to its full extension.

The trajectory from Lev 19:18 (covenant-community neighbor) to Lev 19:34 (extension to the resident alien, grounded in shared vulnerability and memory of oppression) to Jesus's parable of the Good Samaritan (extension to a hated religious-ethnic outsider as moral exemplar) is a coherent, textually-rooted expansion of the same principle on the same stated ground, not three unrelated or contradictory texts — it is progressive revelation operating exactly as classical Christian theology describes it.
