O Adonai, and Ruler of the House of Israel, Who appeared to Moses in the burning bush and gave him the Law on Sinai: Come and with an outstretched arm redeem us.
From Exodus chapter 6 and Micah chapter 5:
Say therefore to the people of Israel, ‘I am the Lord, and I will bring you out from under the burdens of the Egyptians, and I will deliver you from slavery to them, and I will redeem you with an outstretched arm and with great acts of judgment.
But you, O Bethlehem Ephrathah, who are too little to be among the clans of Judah, from you shall come forth for me one who is to be ruler in Israel, whose coming forth is from of old, from ancient days.
O Lord Yahweh, Ruler of Israel, having delivered your people from slavery long ago, you made known your Law so that our more ancient bondage to sin might be fully known. Rule now our hearts that we might hold fast to your Son, who, being born under the law, redeemed us with outstretched arm. Rule, O Lord, until that day when at your coming every knee will bend in homage and every tongue confess your Name. Ame
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.
Emmanuel shall come to thee, O Israel!
