Something to tame

I have seen what words can do, As I deal with people everywhere; The tongue is powerful, it's true! Something to tame and use with care. I've seen spiteful words ruin a life And gentle words heal and bless; I've seen careless words stir up strife And tender words ease distress. I've watched silence speak out loud And idle chatter bring mischief; Seen timely words persuade a crowd And hasty words end in grief. I've seen people eat their words, Who can't seem to hold their tongue; Watched them take the shame it affords When they are later proved wrong. My tongue, too, can go astray, So, Dear Lord, help me watch with care To whom I'd speak and what I'd say, How I'd speak and when and where.
