What is Isaiah 12 and 2 Corinthians 9:7

My Strength and Song 1And you will say in that day, “I thank you, God. You were angry but your anger wasn’t forever. You withdrew your anger and moved in and comforted me. 2“Yes, indeed—God is my salvation. I trust, I won’t be afraid. God—yes God!—is my strength and song, best of all, my salvation!” 3-4Joyfully you’ll pull up buckets of water from the wells of salvation. And as you do it, you’ll say, “Give thanks to God. Call out his name. Ask him anything! Shout to the nations, tell them what he’s done, spread the news of his great reputation! 5-6“Sing praise-songs to God. He’s done it all! Let the whole earth know what he’s done! Raise the roof! Sing your hearts out, O Zion! The Greatest lives among you: The Holy of Israel.” You must each decide in your heart how much to give. And don’t give reluctantly or in response to pressure. “For God loves a person who gives cheerfully.” https://temtube.com/
