'Utter' in the Bible

Where is your wise man? Where your expounder of the Law? Where your investigator of the questions of this present age? Has not God shown the world's wisdom to be utter foolishness?

So likewise ye, except ye utter by the tongue words easy to be understood, how shall it be known what is spoken? for ye shall speak into the air.

Brethren, do not prove yourselves to be children in your minds. As regards evil, indeed, be utter babes, but as regards your minds prove yourselves to be men of ripe years.
