Wells of Salvation

Isaiah 12:3-6
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 peoples,
proclaim that his name is exalted.
 
“Sing praises to the Lord, for he has done gloriously;
let this be made 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.”
