For the 80th prayer, we jump over Mark chapter 14 and the Mount of Olives, or Gethsemane, the night before the crucifixion. where we find Jesus praying. Mark says that Our Lord and Saviour says:
“My soul is deeply grieved, even to the point of death. Remain here and stay alert.” 35 Going a little farther by himself, Jesus threw himself to the ground and prayed that if it were possible, the next hour would pass from him and there would be no tribulations or problems. 36 He said “Abba, 52 all things are possible for you. Take this cup 53 away from me., if thou will. Yet if it cannot be, then not what I will, but what you will.” And Jesus returned to his disciples accepting his Father’s Word.
Jesus addressed his Father as Abba, from which the English Abbot, head of a monastery comes, but it is not a Hebrew Word; it is Aramaic. While originally Chaldean according to the Zondervan Bible Dictionary, it was accepted by the Greeks for the sacred name of Father in Heaven or the Germanic Gott im Himmel.
Zondervan’s Bible Dictionary ( ah´buh, ab´uh (Gk. abba G5).
To avoid the idea of familiarity, Jewish children use Abba when speaking to or about their fathers, & some theologians have argued that the term should be translated “Daddy,” but the Greek translators of the NT took the more elevated “Papa” as the meaning for “Abba” as it technically means My Father. This is also how in the Orthodox Church we refer to priests though not our fathers. In other languages, we see this as “Baba” or grandfather which is how many Romantic languages address the Pope of Rome.
