Dear brethren and friends, our Lord Jesus Christ is the Key of David, meaning that He is Lord of the royal house of David. King David is most notable among the kings of Israel, the second King of a United Israelite Kingdom and ancestor of the kings of Judah the Southern Israelite Kingdom, David is known as a shepherd, warrior, hero, psalmist, and friend of God. God fulfilled His promise to David, that a descendant of David would reign over a United Israel and over all Nations for Eternity. God fulfilled it by sending His Only Son Jesus Christ to be born of the Blessed Virgin Mary a descendant of David who was betrothed to Saint Joseph also a descendant of David.
O come, now Key of David, come
And open wide our heavenly home;
Make safe the way that leads on high,
And close the path to misery.
Rejoice! Rejoice! Emmanuel
Shall come to you, O Israel.
