И было сказано царю Давиду: 'Господь благословил дом Овед-Едома и все, что к нему, из-за ковчега Божия.' И пришел Давид и с радостью поднял ковчег Божий из дома Овед-Едома в город Давидов.
Berakhot
R. Eliezer, the son of R. Jose of Galilee, began [to speak] in honour of the hospitality and expounded : "And the Lord blessed Obed-Edom and all his house...because of the Ark of God" (II Sam. vi. llf.). Can we not use here an a fortiori argument? If the Ark which neither ate nor drank, but which Obed-Edom swept and besprinkled, brought him a blessing, how much more so one who entertains a disciple of the wise, giving him to eat and drink, and allowing him to enjoy his possessions !
