The Meaning of Numbers: The Number 64
The possible meaning of the number 64 is derived primarily from the historical record that underpins Scripture.
In 64 A.D. the Apostle Paul, after being released from prison in Rome, is in the midst of his fifth and final missionary journey. Starting in 63, and running until 67, Paul is determined to keep his promise to himself to visit Spain (Hispania). Writing to the Christians in Rome, he states the purpose of this long trip is to evangelize new areas that have not yet heard the gospel.
But now, there being no place in these regions that has not heard the gospel, and having a great desire to come to you for many years whenever I may go to Spain, I will come to you . . .
Therefore, when I have finished this task, and have safely delivered into their hands the fruit that was collected, I will set off toward Spain . . . (Romans 15:22 - 24, 28).
There is also a possibility that during Paul’s extended evangelistic effort, which included 64 A.D. and ran to 67, he reached Britain (Britannia) and preached the gospel on the island.
Appearances of the number sixty-four
The short book of 2John was written between 63 and 64 A.D. by the Apostle John. It is the third, chronologically, of Apostle John's five manuscripts (his gospel, 1, 2, and 3John plus Revelation) included as part of the New Testament Scriptures.
The book of 1Peter, the Apostle's first of two epistles in the Bible, was written between 64 and 65 A.D.
The Apostle Paul is 64 years old in 66 A.D. In this year, he is toward the latter part of his final missionary journey that will end in 67 with his arrest and imprisonment, yet again, by the Romans.
Protection and the number 64
Psalm 64, written by King David, first asks God for protection against his enemies. He follows up his pleas with a confident declaration that the Eternal will overthrow those who seek to do him harm.
Hear my voice, O God, in my complaint; preserve my life from fear of the enemy. Hide me from the secret counsel of the wicked, from the rebellion of the workers of iniquity,
who sharpen their tongue like a sword and bend their bows to shoot their arrows, even bitter words . . . But God shall shoot at them with an arrow; suddenly they shall be wounded (verses 1 - 3, 7 of Psalm 64).
