Receiving someone not personally known to the household involved both generosity and judgment. Travelers needed assistance, but hosts also had to decide whom to trust and how much responsibility to assume.
Israel's Scriptures repeatedly remind the people of their own experience as strangers and command just and compassionate treatment of outsiders living among them.
A stranger might request water, food, directions, shelter, or help locating relatives or associates. Hospitality could temporarily bring that person within the protection and care of a household.
The movement of strangers is visible indirectly through roads, imported objects, coins, ports, pilgrimage facilities, and evidence of regional and long-distance travel.
Biblical, Jewish, Greco-Roman, and Christian texts discuss strangers, foreigners, travelers, hospitality, suspicion of outsiders, and moral obligations toward people away from home.
The command to love and protect the stranger is deeply rooted in the Law, which reminds Israel that the people themselves had once been strangers in Egypt.
Jesus expands concern for outsiders in teachings such as the Good Samaritan and identifies welcoming the stranger with serving Him in Matthew 25.
Jewish Scripture strongly encouraged concern for strangers and vulnerable outsiders, while practical hospitality remained dependent upon real social circumstances.
Ancient concern for strangers did not eliminate normal caution about unknown travelers or erase distinctions between different kinds of outsiders.
Hospitality toward strangers shows how biblical love could extend beyond family and familiar neighbors to people who could offer little immediate security or advantage in return.
