‘Take the helmet of salvation and the sword of the Spirit, which is the word of God’ - Ephesians 6:17

The famous figure of speech in which Paul compares the life of a Christian with a Roman soldier, found in Ephesians 6, would almost certainly have had Hebraic connotations in the mind of Paul. As a prisoner, possibly in Herod’s palace at Caesarea, and under Roman guard, the analogy was undoubtedly a fitting one, and yet Paul may have also been drawing upon a passage found in Isaiah 59 concerning the end time coming of Yahweh.
