What is the Biblical justification that God controls every detail of the future?

What is the Biblical justification that God controls every detail of the future (as accepted by Reformed Theology)? I'm sure that this has been asked, but I can't find it. Tim Keller cites two verses from Proverbs 16. >The plans of the heart belong to man, but the answer of the tongue is from the Lord. - Proverbs 16:1 >The heart of man plans his way, but the Lord establishes his steps. - Proverbs 16:9. I think I have found both a better exposition of my question and the answer here - https://christianity.stackexchange.com/q/4098/102058 My thanks to Mike Borden for giving me the word, "sovereignty", which led me to this question and answers.
