Luke 1:68

Εὐλογητός. This hymn of praise is hence called the BENEDICTUS. It is expressed (as was natural) almost exclusively in the language of ancient prophecy, Psalms 98:3; Psalms 105:8-9; Psalms 132:17; Isaiah 9:2; Isaiah 40:3; Ezekiel 16:60, &c. It has been in use in Christian worship perhaps as far back as the days of St Benedict in the sixth century, and it was early recognised that it is the last Prophecy of the Old Dispensation, and the first of the New, and furnishes a kind of key to the evangelical interpretation of all prophecies. It is also a continual acknowledgement of the Communion of Saints under the two dispensations; for it praises God for the salvation which has been raised up for all ages out of the house of His servant David, and according to the ancient covenant which He made with Abraham (see Romans 4:11; Galatians 3:29).
