Our Lord and Master gave us a number of rules for living the whole of the word. Some of them were indirect and stated in His parables. But some of them were direct. Technically, everything in the whole Book is from Jesus (all the words should be in red!) but here we are just speaking of what Jesus said directly during His incarnation at the temptation in the desert.
When confronted by evil, Jesus shows us practical defense. In Matthew chapter four, He made three statements to counter the Satan’s temptations, and all three statements came from “what is written” meaning Torah or the Law.
4But He answered and said, “It is written, ‘Man shall not live on bread alone, but on every word that proceeds out of the mouth of God.’ ” (Matthew 4:4 NASB95)
7Jesus said to him, “On the other hand, it is written, ‘You shall not put the Lord your God to the test.’ ” (Matthew 4:7 NASB95)
10Then Jesus said to him, “Go, Satan! For it is written, ‘You shall worship the Lord your God, and serve Him only.’ ” (Matthew 4:10 NASB95)
Each response is saying essentially the same thing in three different ways. On the surface what looks like three different temptations have the same goal. The Satan tries to get Jesus to abandon God’s will and do His own thing (in reality the Satan’s own thing).
We still get hammered with the same sort of temptations on a regular basis, and the defense used by the Master works just as well now as it did then.
