Verses 1 to 3 of John 18.

After saying these things, Jesus crossed the Kidron Valley with his disciples and entered a grove of olive trees. Judas, the betrayer, knew this place, because Jesus had often gone there with his disciples. The leading priests and Pharisees had given Judas a contingent of Roman soldiers and Temple guards to accompany him. Now with blazing torches, lanterns, and weapons, they arrived at the olive grove.
