'Traveler' in the Bible

When he looked up and saw the traveler in the city square, the old man asked, “Where are you going, and where do you come from?”

Now a traveler came to the rich man, but the rich man could not bring himself to take one of his own sheep or cattle to prepare for the traveler who had come to him. Instead, he took the poor man’s lamb and prepared it for his guest.

No stranger had to spend the night on the street,for I opened my door to the traveler.

Hope of Israel,its Savior in time of distress,why are You like a foreigner in the land,like a traveler stopping only for the night?
