Perhaps someone can put them on this thread.
Mat 4:4
But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God.
Matthew 4:5
Then the devil taketh him up into the holy city, and setteth him on a pinnacle of the temple,
Mat 4:6
And saith unto him, If thou be the Son of God, cast thyself down: for it is written, He shall give his angels charge concerning thee: and in [their] hands they shall bear thee up, lest at any time thou dash thy foot against a stone.
Mat 4:7
Jesus said unto him, It is written again, Thou shalt not tempt the Lord thy God.
The quote to which you refer originates from Satan's temptation of Christ in the desert. Both Satan and Christ knew that God existed, so it was not a matter of trying to prove or disprove so. The context and purpose of the discussion was (a) Satan tempting Christ to cast himself down to the Stones (killing himself), inferring that all of the Angels in heaven would prevent Christ from dying (which, we see from the Crucifixion, was a false inferrence), and (b) Christ rejecting the lies and distortions which Satan made (the text which Satan quoted did not say what he implied it did, but was a distortion of the orginal meaning - kinda like what the liberals in the Methodist and Episcopal church are doing today).
The entire episode can be found in Matthew Chapter 4, 1-11. That was one of the THREE temptations brought upon Christ directly by Satan himself.
