O come, thou Lord of might

Latin translation of O Adonai
O Lord and leader of the House of Israel, who appeared to Moses in the fire of the burning bush and gave him the law on Sinai: Come and redeem us with an outstretched arm.

Advent Carol
O come, O come, thou Lord of might, who to thy tribes on Sinai's height in ancient times didst give the Law in cloud and majesty and awe. Rejoice, rejoice. Emmanuel shall come to thee, O Israel.

The antiphon today is based on the manifestation of God on Mount Sinai in the Book of the Exodus. God gave the Ten Commandments to Moses, and the Torah (or "Law of Moses") became both the foundation of Jewish faith and life as well as the dawn of ethical monotheism in world history.

Jesus said, "Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them" (Matthew 5:17). The Messiah was seen as one who would represent the rule of God's law and bring it to fulfillment (see Isaiah 11:4-5). As Lord, "he must reign until he has put all his enemies under his feet" (1 Corinthians 15:25). As Savior, Jesus fulfilled the obligations of the Law on behalf of sinners (see Romans 8:1-4).
