'Strangers' in the Bible

A minister then must be a man of irreproachable character, true to his one wife, temperate, sober-minded, well-behaved, hospitable to strangers, and with a gift for teaching;

She must have been true to her one husband, and well reported of for good deeds, as having brought up children, received strangers hospitably, washed the feet of God's people, given relief to the distressed, and devoted herself to good works of every kind.
