'Tongues' in the Bible

The hearts of reckless people will understand sound judgment, and the tongues of those who stammer will be ready to speak clearly.

then the lame will leap like deer, and the tongues of speechless people will sing for joy. Yes, waters will gush forth in the wilderness, and streams will run through the desert;

"As for the poor, the needy, those seeking water when there is none and their tongues are parched from thirst I, the LORD, will answer them. I, the God of Israel, won't abandon them.
