What does Luke 22:47 mean?
Jesus has been praying in the garden of Gethsemane on the Mount of Olives. While He prays, the disciples sleep. At least twice, He has awakened them, telling them to pray so they don't fall into temptation. But now, their chance to prepare themselves is over (Luke 22:39–46; Matthew 26:36–46).Pharisees and those loyal to Herod Antipas have been trying to destroy Jesus since the beginning of His ministry (Mark 3:6). The Pharisees hate Him because He doesn't support their extra-biblical rules. The Sadducees join in because His miracles make Him so popular. Of note is how He raised Lazarus from the dead (John 11:45–53). Then His triumphal entry and the cleansing of the temple sent the different groups on a crusade to tear down His authority; they all failed (Luke 19—20). Opposition to Jesus has joined the Pharisees, Sadducees, Herodians, and elders of Jerusalem to a single purpose: to eliminate Him.
The biggest obstacle to this is that the people love Jesus. If the religious and civil leaders arrest Him, the people will riot and kill them (Luke 22:2). Fortunately for them, Judas, one of Jesus' closest disciples, agrees to betray Jesus in a quiet place, away from the crowds (Luke 22:3–6). During the Last Supper, Jesus tells Judas it is time and dismisses him (John 13:26–27).
Judas has gone to the chief priest. The priests have given him servants and members of the temple guard. Judas knows that Jesus spends His nights on the Mount of Olives. It's dark. The disciples are groggy with sleep. Judas leads the guards, armed with swords and clubs, to Jesus (Mark 14:43).
Judas cries, "Rabbi!" and kisses Jesus (Mark 14:45). Jesus wants Judas to feel the weight of what he is doing. Kissing one's teacher is a sign of honor. Judas uses it as a sign for the guards to identify which dark shape on a dark mountain they have come for. Judas doesn't fully understand until he realizes the priests, scribes, and elders don't merely want to arrest Jesus; they want Him dead (Matthew 27:3–5).
Hundreds of years before, David described the heartbreak of this moment:
For it is not an enemy who taunts me—
then I could bear it;
it is not an adversary who deals insolently with me—
then I could hide from him.
But it is you, a man, my equal,
my companion, my familiar friend.
We used to take sweet counsel together;
within God's house we walked in the throng (Psalm 55:12–14).
