This is ὑμεῖς, the nominative plural form of the second person pronoun, meaning 'you' as the subject when addressing a group. Greek's rich pronoun system distinguished singular from plural second person, and the nominative case marked who was performing the action. New Testament writers used it emphatically to contrast audiences with others: 'you are the light of the world,' 'you, however, are not in the flesh.' The form could stand alone for emphasis ('you yourselves know') or accompany verbs where English would simply say 'you.' It marked collective identity and responsibility in apostolic instruction to communities of believers.
