The Monastery of the Qurantul sits on top the Mount of Temptation outside of modern day Jericho. The Mount of Temptation is the sight where the devil tempted Jesus for 40 days.
Matthew 4:1-11 New International Version (NIV)
Jesus Is Tested in the Wilderness1 Then Jesus was led by the Spirit into the wilderness to be tempted 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.’ ”
5 Then the devil took him to the holy city and had him stand on the highest point of the temple. 6 “If you are the Son of God,” he said, “throw yourself down. For it is written:
“‘He will command his angels concerning you,
and they will lift you up in their hands,
so that you will not strike your foot against a stone.’ ”
7 Jesus answered him, “It is also written: ‘Do not put the Lord your God to the test.’ ”
8 Again, the devil took him to a very high mountain and showed him all the kingdoms of the world and their splendor. 9 “All this I will give you,” he said, “if you will bow down and worship me.”
10 Jesus said to him, “Away from me, Satan! For it is written: ‘Worship the Lord your God, and serve him only.’ ”
11 Then the devil left him, and angels came and attended him.
