'Letting' in the Bible

And the ship being caught and driven, and not able to bring her head to the wind, letting her go we were driven before it.

Now these things, brethren, I have transferred, in their application, to myself and Apollos, for your sakes, that ye may learn in us the lesson of not letting your thoughts go above what is written, that ye may not be puffed up one for such a one against another.
