For being omnipotent, omniscient, et. al. God sure has to ask a lot of questions that he would know the answers to if he were omniscient.
Genesis 3:9 And the LORD God called unto Adam, and said unto him, Where art thou?
(My personal favorite - there are no other people god has to keep track of but Adam and Eve yet even though god is with them in the garden of eden and even though adam is only hiding "amongst the trees", god has to ask ... "where are you?")
Genesis 3:11 And he said, Who told thee that thou wast naked? Hast thou eaten of the tree, whereof I commanded thee that thou shouldest not eat?
(Possibly retorical but why a question? Why not an imperitave statement? Why not "Thou hast eaten...."? And Adam answers in the next verse. Adam doesn't take the question to be retorical. Having sinned already, Adam should have lied. Look at all the misery and suffering that would have been avoided.)
Job 1:7 And the LORD said unto Satan, Whence comest thou? Then Satan answered the LORD, and said, From going to and fro in the earth, and from walking up and down in it.
(the LORD is apparently unable to keep tabs on the worst entity in the universe)
Numbers 22:9 And God came unto Balaam, and said, What men are these with thee?
