James 3:5

For the choir director. For Jeduthun. A Psalm of David. I said, “I will keep watch over my ways That I may not sin with my tongue; I will keep watch over my mouth as with a muzzle While the wicked are in my presence.”

If anyone thinks himself to be religious while not bridling his tongue but deceiving his own heart, this man’s religion is worthless.

For we all stumble in many ways. If anyone does not stumble in what he says, he is a perfect man, able to bridle the entire body as well.
