ISB ~ Luke 21 v15

a mouth and wisdom:Unlike professional orators who rehearse their speeches before delivering them, disciples should only prepare to be faithful. Christ will give them words through the Holy Spirit (Mt 10:20; Mk 13:11). Stephen was an example of this by his powerful witness in Jerusalem (Acts 6:9-10), as were other early Christians (Acts 4:8-14; 26:24-32).
