There is a portion of Bible scripture in Matthew (26:36-56) that has always left me wondering. It’s where Jesus goes into the garden of Gethsemane to pray. The gospel writer goes into considerable detail about what happened …
36 Then Jesus went with them to a place called Gethsemane; and he said to his disciples, “Sit here while I go over there and pray.” 37 He took with him Peter and the two sons of Zebedee, and began to be grieved and agitated. 38 Then he said to them, “I am deeply grieved, even to death; remain here, and stay awake with me.” 39 And going a little farther, he threw himself on the ground and prayed, “My Father, if it is possible, let this cup pass from me; yet not what I want but what you want.” 40 Then he came to the disciples and found them sleeping; and he said to Peter, “So, could you not stay awake with me one hour? 41 Stay awake and pray that you may not come into the time of trial; the spirit indeed is willing, but the flesh is weak.”42 Again he went away for the second time and prayed, “My Father, if this cannot pass unless I drink it, your will be done.” 43 Again he came and found them sleeping, for their eyes were heavy. 44 So leaving them again, he went away and prayed for the third time, saying the same words. 45 Then he came to the disciples and said to them, “Are you still sleeping and taking your rest? See, the hour is at hand, and the Son of Man is betrayed into the hands of sinners. 46 Get up, let us be going. See, my betrayer is at hand.” (From the New Revised Standard Edition)
Note that there are three instances in which Jesus retreats into the garden of Gethsemane to pray. Each time he requests the disciples to stay awake while he is gone … and each time he returns to find them sound asleep.
What I have never been able to figure out is how did the gospel writer know what Jesus prayed if the disciples were asleep the entire time?
