The first Christian song, non-liturgical, I remember learning was El Shaddai by Amy Grant. The song recounted the covenant of Abraham and our Lord with the refrain using two very specific names for God: El Shaddai (God of the Mountain) and Adonai (Master, Owner or the Lord). These titles have been engrained in my life of prayer and have been great sources of meditation and solace.
Today, the revelation of our Lord through the O Antiphons focuses on the name Adonai. This title is first found in Genesis 15:2 where Abraham addresses God as “Adonai YHWH.” It is used approximately 300 times in the Tanakh. Vespers recounts His saving power this way:
O Lord and Ruler the house of Israel, who appeared to Moses in the flame of the burning bush and gave him the law on Sinai: come, and redeem us with outstretched arms.
May the Adonai rule your heart bring peace to the kingdom of your heart and family. For the Lord Himself will go before you (Deuteronomy 31:8), defend you as the Valiant Warrior (Jeremiah 20:11a) and shepherd (Genesis 49:25; also Isaiah 1:24; 49:26b; cf. 60:16b) you into a lnd flowing with milk and honey.
