'Deserving' in the Bible

Whatever city or village you enter, ask who in it is worthy [who welcomes you and your message], and stay at his house until you leave [that city].

If [the family living in] the house is worthy [welcoming you and your message], give it your [blessing of] peace [that is, a blessing of well-being and prosperity, the favor of God]. But if it is not worthy, take back your blessing of peace.
