'Speaks' in the Bible

For all of us make many mistakes. If someone does not make any mistakes when he speaks, he is perfect and able to control his whole body.

Think ye that the scripture speaks in vain? Does the Spirit which has taken his abode in us desire enviously?

Speak not against one another, brethren. He that speaks against his brother, or judges his brother, speaks against the law and judges the law. But if thou judgest the law, thou art not doer of the law, but judge.
