God promised to the house of Israel that he would one day send them a great king that would defeat all evil and rule over all the nations. This king is Jesus Christ. Through his death and resurrection, he has fulfilled his promises to Israel and defeated all evil. Through the Church, he has brought the knowledge of this victory to the ends of the earth.
O sing to the Lord a new song, for he has done marvelous things! His right hand and his holy arm have gotten him victory. The Lord has made known his victory, he has revealed his vindication in the sight of the nations. He has remembered his steadfast love and faithfulness to the house of Israel. All the ends of the earth have seen the victory of our God.
Christ is risen from the dead,
By death trampling down on death,
And to those in the tomb,
He has granted life!
