What is the Biblical Basis that God does not know every detail of the future?

What are the Biblical arguments used by those who teach that God does not know every detail of the future? I've seen three answers as to whether God knows every detail of the future. - 1. "God knows every detail of the future, including things that He hasn't planned". 2. "God knows every detail of the future because He plans every detail of the future". 3. "While God could control every detail of the future, He does not, and sometimes things happen that He does not expect to happen". A complete response should discuss all three.
