Humeis (G5210) is the second person plural personal pronoun: 'you all' or 'you' (plural). While English merges singular and plural 'you,' Greek preserves the distinction. Humeis addresses a community, a group — stressing collective identity and responsibility.
Many NT commands use humeis — you all as a community. 'You (humeis) are the salt of the earth' (Matthew 5:13) and 'You (humeis) are the light of the world' (Matthew 5:14) address the collective community of disciples. 1 Corinthians 3:16 — 'Don't you (humeis) know that you (humeis) are God's temple?' — grounds individual holiness in corporate identity. The church's existence is radically communal: the 'you' of the NT is almost always plural.
