A participle meaning 'dwelling among' or 'living in the midst of'—residing within or among a group. 2 Peter 2:8 describes righteous Lot 'dwelling among' the people of Sodom, whose lawless deeds tormented his righteous soul. The term emphasizes physical proximity and ongoing residence. Classical Greek used it for inhabiting a place or living among a people. Peter's point is that Lot's geographical location didn't corrupt him—he maintained righteousness despite constant exposure to wickedness, proving God can preserve the godly even in ungodly environments.
