Benedictus
Benedictus, the thanksgiving of Zacharias on the birth of his son, John the Baptist (Luke i. 68-79), used at Morning Prayer from the ninth century onward, and coming into the Anglican Prayer Book from the Sarum Breviary. It is now the Canticle appointed for use after the Second Lesson. The text in our Prayer Book is nearest to Tyndale's translation of the Bible, but does not precisely coincide with any.
