'Knowledge' in the Bible

Talk no more so exceeding proudly; let not arrogancy come out of your mouth: for the LORD is a God of knowledge, and by him actions are weighed.

See therefore, and take knowledge of all the lurking places where he hideth himself, and come ye again to me with the certainty, and I will go with you: and it shall come to pass, if he be in the land, that I will search him out throughout all the thousands of Judah.
