Matthew 4:1-4
Jesus Is Tested in the Wilderness
4 Then Jesus was led by the Spirit into the wilderness to be tempted[a] by the devil. 2 After fasting forty days and forty nights, he was hungry. 3 The tempter came to him and said, “If you are the Son of God, tell these stones to become bread.”
4 Jesus answered, “It is written: ‘Man shall not live on bread alone, but on every word that comes from the mouth of God.’[b]”
Deuteronomy 8:2
2 Remember how the Lord your God led you all the way in the wilderness these forty years, to humble and test you in order to know what was in your heart, whether or not you would keep his commands.
