Adjective xenos (stranger, foreign) in the Gospels-Acts

(Translation from NRSV with a few modifications for a more literal meaning)

Matthew

25: 35for I was hungry and you gave me food, I was thirsty and you gave me something to drink, I was a stranger (xenos) and you welcomed me,
25: 38And when was it that we saw you a stranger (xenos) and welcomed you, or naked and gave you clothing?
25: 43I was a stranger (xenos) and you did not welcome me, naked and you did not give me clothing, sick and in prison and you did not visit me.'
25: 44Then they also will answer, 'Lord, when was it that we saw you hungry or thirsty or a stranger (xenos) or naked or sick or in prison, and did not take care of you?'
27: 7After conferring together, they used them to buy the potter's field as a place to bury foreign (xenos) people.

Acts

17: 18Also some Epicurean and Stoic philosophers debated with him. Some said, "What does this babbler want to say?" Others said, "He seems to be a proclaimer of foreign (xenos) divinities." (This was because he was telling the good news about Jesus and the resurrection.)
17: 21Now all the Athenians and the foreign (xenos) peope living there would spend their time in nothing but telling or hearing something new.

3 John

1: 5Beloved, you do faithfully whatever you do for the friends, even though they are strangers (xenos) to you;
