'Turned' in the Bible

And I turned myself to behold wisdom, and madness, and folly: for what can the man do that cometh after the king? even that which hath been done long ago.

Therefore I turned about to cause my heart to despair concerning all the labor wherein I had labored under the sun.

I turned about, and my heart was set to know and to search out, and to seek wisdom and the reason of things , and to know that wickedness is folly, and that foolishness is madness.
