Luke 2:29

Now lettest thou thy servant depart, Lord, According to thy word, in peace; For mine eyes have seen thy salvation, Which thou hast prepared before the face of all peoples; A light for revelation to the Gentiles, And the glory of thy people Israel.

This passage carries the imagery of a bondservant requesting of his master that he might be dismissed. Simeon recognized that in the giving of Christ, God had indeed accomplished the salvation of men inclusive of the Gentiles. That Jesus was indeed the glory of Israel is fully true; but the Israel of this promise is far more extensive than secular or national Israel, and encompasses the redeemed of all ages.
