4) δώδεκα – twelve (total occurrences NT: 75)
- no Pauline parallel
- related to the disciples the usual phrases in the NT are „the 12“ or „the 12 disciples or apostles“
- the „12“: primarily in Markan material, Luke followed closely,
- 12 apostles, disciples: Mt 10:1, Mt 10:2, Mt 11:1, (Mt 20:17), Rev 21:14
- note that nowhere in the synoptics it is claimed that „the 12“ saw Jesus, Acts has only „the 11“ without Judas
