What does Judaism teach about obligations toward strangers and non-Jews?

Judaism holds strong obligations toward the stranger (ger in the sense of the vulnerable outsider) — repeated in the Torah — and toward non-Jews through the Noahide framework and basic ethical duties. How these apply in detail is debated, but care for the stranger is a central, repeated value.

This is a core ethical question and a corrective to caricatures; the stranger-command is one of the Torah's most repeated.

Here: the stranger / vulnerable outsider (a different sense than 'convert').

• Biblical: love and care for the stranger, repeatedly commanded.
• Rabbinic: obligations to non-Jews through universal ethics and the Noahide framework.

The stranger-command recurs dozens of times in the Torah; the rabbis extended ethical obligations beyond the Jewish community.
