Well, it's Isaiah 12. This one's a real hum-dinger. So, God's like, "Hey, I'm gonna make things better for you, and you'll be so happy you'll sing and shout!" Except, it's not just singing and shouting - no, that would be too easy. Instead, it's singing and shouting and doing weird hand gestures, and then bowing down to God. But it's cool, because then God will make you feel safe and provide you with water, and you'll be happy, and it'll all be okay. So, there you have it: Isaiah 12. Sing, shout, and wave your hands around - that's the way to do it.
