'Man shall not live by bread alone, but by every word that proceeds from the mouth of God.'

Matthew 4:1-11

At that time, Jesus was led up by the Spirit into the wilderness to
be tempted by the devil. And He fasted forty days and forty nights,
and afterward He was hungry. And the tempter came and said to Him,
"If you are the Son of God, command these stones to become loaves of
bread." But He answered, "It is written, 'Man shall not live by bread
alone, but by every word that proceeds from the mouth of God.'" Then
the devil took Him to the holy city, and set Him on the pinnacle of
the temple, and said to Him, "If you are the Son of God, throw
yourself down; for it is written, 'He will give His angels charge of you,'
and 'On their hands they will bear you up, lest you strike your foot
against a stone.'" Jesus said to him, "Again, it is written, 'You shall
not tempt the Lord your God.'" Again, the devil took Him to a very
high mountain, and showed Him all the kingdoms of the world and the
glory of them; and he said to Him, "All these I will give you, if you
will fall down and worship me." Then Jesus said to him, "Be gone,
Satan! for it is written, 'You shall worship the Lord your God and Him
only shall you serve.'" Then the devil left Him, and behold, angels
came and ministered to Him.
