In Matthew 26:31-75 Jesus predicted Peter’s denial. After finishing the Last Supper they all moved on to the Mount of Olives, and there was the garden of Gethsemane. In the garden Jesus prayed “Not my will, but yours be done.” Jesus prayed this prayer three times, and every time the disciples fell asleep. After that is recorded the betrayal and arrest of Jesus as he was taken to the Sanhedrin to be interrogated. The chapter ends with Peter’s denial.
Deuteronomy 28. The LORD through Moses specified many blessings for obedience and even more curses for disobedience.
