King James Version
And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ.New International Version
Brothers, I could not address you as spiritual but as worldly--mere infants in Christ.Catholic Public Domain Version
And so, brothers, I was not able to speak to you as if to those who are spiritual, but rather as if to those who are carnal. For you are like infants in Christ
