O Adonai

Each Day from Dec. 17 to Dec 23 has its own liturgical Antiphon of a Title of Jesus from the OLD TESTAMENT.  Since each Antiphon begins with "O", they are called the "O Antiphons".  The Title for today is:   O Adonai.   This is Hebrew from "O Lord".   Since the Name of God (YHWH) is SO holy nobody was allowed to say it verbally, so when it came up in the biblical text they would say:  Adonai (Lord) in reference to God.

In the New Testament the title Lord was given to Jesus.  In Greek this would have been "Kyrios".   In the Liturgy we will often sing:   Kyrie eleison, Christe eleison, Kyrie elesion:  Lord have mercy, Christ have mercy, Lord have mercy.

I would encourage you to pray with the antiphon, and meditaton on Jesus as Lord.  Here is the Antiphon:

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.

It is good to read this in light of Isaiah 33:22 "For the Lord is our judge, the Lord is our ruler, the Lord is our king; he will save us."

Peace
