A few scriptures exhorting hospitality:
Contribute to the needs of the saints and seek to show hospitality. (Romans 12:13 ESV)
Let brotherly love continue. Do not neglect to show hospitality to strangers, for thereby some have entertained angels unawares. (Hebrews 13:1 ESV)
Above all, keep loving one another earnestly, since love covers a multitude of sins. Show hospitality to one another without grumbling. As each has received a gift, use it to serve one another… (1 Peter 4:8-10 ESV)
