Matthew 26 and Mark 14 describe Jesus entering Gethsemane with His disciples after the Last Supper. Taking Peter, James, and John farther with Him, Jesus became deeply sorrowful and prayed that, if possible, the cup before Him might pass, while submitting Himself to the Father's will.
Luke 22 describes His anguish and prayer on the Mount of Olives. John 18 states that Jesus crossed the Kidron Valley with His disciples and entered a garden that Judas also knew because Jesus had often met there with His followers.
Judas arrived with an armed party and identified Jesus, leading to His arrest and the sequence of trials culminating in the crucifixion.
