Warm hospitality

Judges 19:1-15
Levits had concubine in the hill country of Ephraim.
The Levites and his concubine and his servant traveled to Israelite city Gibeah in Benjamin, but no one took them into his home for the night.
Why?
Levite has concubine shows they live in lawless country.
People are not care about the foreigner against the word of the Lord.
The warm traditional hospitality of the concubine's father contrasts with the lack of it at Gibeah.
Warm hospitality is needed to me to welcome everyone come to my home.
How?
Have mercy to the others because I am a traveler in this world either.
