December 18 -O Sacred Lord
O Sacred Lord of ancient Israel, who showed yourself to Moses in the burning bush, who gave him the holy law on Sinai mountain: Come, stretch
out your mighty hand to set us free. O Leader of the House of Israel, giver of the Law to Moses on Sinai: come to rescue us with your mighty power! O Come, O Come, Thou Lord of might, who to thy tribes on Sinai's height in ancient times didst give the law.
