First Sunday In Lent

Our Lord Jesus Christ, directly after His baptism, prepared Himself for His public life and mission by a fast of forty days in the desert, which extends from Jericho to the Mountains of Judea. Let us prepare ourselves by fast, prayers and works of charity for the solemn Feast of Easter.
The Roman Missal, 1964

At that time Jesus was led by the Spirit into the desert, to be tempted by the devil. And when He had fasted forty days and forty nights, afterwards He was hungry.

And the tempter coming said to Him: If Thou be the Son of God, command that these stones be made bread. Who answered and said: It is written: Not in bread alone doth man live, but in every word that proceedeth from the mouth of God.

Then the devil took Him up into the holy city and set Him upon the pinnacle of the temple, and said to Him: If Thou be the Son of God, cast Thyself down. For it is written: That He hath given his Angels charge over Thee, and in their hands shall they bear Thee up, lest perhaps Thou dash Thy foot against a stone. Jesus said to him: It is written again, Thou shalt not tempt the Lord thy God.

Again the devil took Him up into a very high mountain and showed Him all the kingdoms of the world and the glory of them, and said to Him: All these will I give Thee, if falling down Thou wilt adore me. Then Jesus saith to him: Begone, Satan! for it is written: The Lord Thy God shalt thou adore, and Him only shalt thou serve.

Then the devil left Him. And behold Angels came, and ministered to Him.
St. Matthew 4. 1-11
