Zechariah praises God, characterizing God as powerful and faithful to covenantA covenant is a promise or agreement. In the Bible the promises made between God and God's people are known as covenants; they state or imply a relationship of commitment and obedience. More promises. Zechariah also declares that his son, John, will play an important but subordinate role in the story that will unfold.
Zechariah’s extended statement of praise (often called the Benedictus, the first word of the Latin translation of his statement) comes in response to his son John’s birth and the return of his ability to speak. As with the other two “canticles” in LukeThe "beloved physician" and companion of Paul More 1-2 (the Magnificat and the Nunc dimittis), the words of the Benedictus come from numerous passages in the Old Testament.
The Benedictus divides into two parts. The first speaks about the works of God (vv. 68-75). Here Zechariah praises God for delivering Israel from its enemies and for remembering covenants that God has made in the past. Zechariah describes the current events–that is, the coming of John and Jesus–as evidence that God has remembered and is acting on behalf of God’s chosen people. The second part (vv. 76-79) turns attention toward John, directly addressing him. It states clearly that John and JesusJesus is the Messiah whose life, death, and resurrection are God's saving act for humanity More are not equals; instead, John is the prophet and forerunner of the Lord Jesus, who will be God’s means of bringing peace to God’s people.
Luke explicitly introduces the Benedictus as “prophecy” in v. 67. Zechariah views the present events concerning John and Jesus through the lens of God’s faithfulness. The births of these two babies are part of the story of a God who keeps promises and acts on behalf of the people of Israel.
