Isaiah 12:3-6 (Eve of the Theophany)
With joy you will draw water from the wells of salvation. And you will say in that day: "Give thanks to the LORD, call upon his name; make known his deeds among the nations, proclaim that his name is exalted. "Sing praises to the LORD, for he has done gloriously; let this be known in all the earth. Shout, and sing for joy, O inhabitant of Zion, for great in your midst is the Holy One of Israel."
