Acts 5:13

The rest. Unbelievers, deterred by the fate of Ananias from uniting themselves to the church under false pretenses.

Join himself [κ ο λ λ α σ θ α ι]. See on Luke 14:15; Luke 10:11. In all but two instances (Romans 12:9; 1 Corinthians 6:17), the word implies a forced, unnatural, or unexpected union. Thus Philip would not, without a special command, have "joined himself" to the chariot of the Ethiopian prince (Acts 8:29). Saul's attempt to join himself to the apostles was regarded by them with suspicion (Acts 9:26); and the fact that certain persons "clave to" Paul in Athens is expressly contrasted with the attitude of the citizens at large. The sense of an unnatural union comes out clearly in 1 Corinthians 6:16.
