Hebrews 13:1-4

Let love of the brethren continue. Do not neglect to show hospitality to strangers, for by this some have entertained angels without knowing it. Remember the prisoners, as though in prison with them, and those who are ill-treated, since you yourselves also are in the body. Marriage is to be held in honor among all, and the marriage bed is to be undefiled; for fornicators and adulterers God will judge.
