Variety: Leviticus 25v23

The land is mine and you reside in my land as foreigners and strangers. Leviticus 25:23

Biblical scholar Ched Myers writes of the prominence of immigrants in the Scriptures. 

Torah and the Prophets warned Israel not to discriminate against economic or political refugees, since in YHWH’s eyes even the chosen people were “but aliens and tenants” (Leviticus 25:23). Instead, they were to treat the “sojourners in your midst” with dignity and justice (Deuteronomy 24:14). This fundamental regard for the resident alien, and call to solidarity with the “outsider,” came to full realization in the teaching and practice of Jesus of Nazareth. An oft-cited verse that captures this is Matthew’s last-judgment parable, in which Jesus commends those who welcome him in the guise of a stranger—and condemns those who do not (Matthew 25:35–46). [1] 

Three archetypally vulnerable groups are commonly named in almost formulaic fashion: widows, orphans, and strangers. Because YHWH “watches over” them (Psalm 146:9), they have intrinsic rights to sustenance (Deuteronomy 14:29, 24:19–21, 26:12–13) and to human rights (Deuteronomy 27:19; Psalm 94:6). And the prophets measure the health of the nation by how widows, orphans, and strangers are treated (Jeremiah 7:6, 22:3; Zechariah 7:10; Malachi 3:5)….  

But there is another, theologically startling characteristic of scripture: from beginning to end, God too is portrayed entering our world in the guise of a stranger in need of hospitality. One of the first divine epiphanies is YHWH’s mysterious appearance in the form of “three guests” (Genesis 18:1–8). Abraham and Sarah offer them food, drink, and shelter, and their hospitality occasions the great promise of progeny that launches the salvation story of an entire people (Genesis 18:9–10)…. 

We can go further: the God of the Bible is consistently portrayed as “stateless,” and we can reasonably add undocumented. This is in stark contrast to the patron-gods of the empires that surrounded Israel, who lived comfortably in the temples of the king. In the Exodus tradition, the wilderness God doesn’t even have a name, much less “papers”: the moniker YHWH means “I will be whoever I will be” (Exodus 3:14). God’s voice summons Moses into a conspiracy for freedom from a burning bush outside the borders of, and in opposition to, Pharaoh’s political and economic system. Inspired and led by this God, the Hebrews flee Egypt “in haste” (Exodus 12:33), and wander in the desert as a people with no legal status—as political refugees still must do.  

The Gospel writers portray Jesus as a refugee in need of hospitality:  

The Second Testament continues in this tradition. The gospel story begins with Jesus’ family fleeing violence as political refugees, pushed around Palestine by the imperial forces of Caesar and Herod (Matthew 2; Luke 2). The adult Jesus not only characterizes himself as homeless (“the Human One has nowhere to lay his head,” Luke 9:58), but stateless. “My kingdom is not of this world,” he says before the Roman procurator (John 18:36). The evangelists also portray Jesus as a constant recipient of hospitality who sometimes even “invites himself in” (see, for example, Luke 19:5). [2]
