The Meaning of Numbers: The Number 63
The possible meaning of the number 63 is derived from both history and events in Scripture.
The Greek word Agapao, Strong's #G25, is recorded 63 times in the original language version of the four gospels. Agapao, which is usually translated as the English word "love" or "loved" in the King James translation, is one of a few types of love described in God's word. Not surprisingly, John's gospel uses this Greek word the most with 37 occurrences.
2John, written between 63 and 64 A.D., is the sixty-third book found in most modern translations. It is the third, chronologically, of Apostle John's five manuscripts included as part of the New Testament Scriptures.
2John is unique in that it contains the fewest number of verses of any book in Scripture with only 13 found in a single chapter. John's fourth writing, 3John, contains only 14 verses.
Appearances of the number sixty-three
Only the books of Psalms and Isaiah have more than 63 chapters. Joshua 15 and Ezekiel 16 have exactly sixth-three verses.
The sixth most mentioned animal in scripture is fish. The word fish or its plural is found 63 times in Scripture.
Roman troops, in 63 B.C., led by General Pompey, occupy the Holy Land in the name of the Roman Republic. The Republic attacks and conquers Jerusalem.
The number 63 and Paul
The Apostle Paul was sixty-three years old in 65 A.D. In this year he was in the middle of his fifth and final missionary journey, preaching the gospel in Spain (Romans 15:22 - 24, 28) and (likely) Britain. The island of Britain was conquered by the Roman Empire in 43 A.D. under Emperor Claudius and established as the province of Britannia.
But now that there is no more place for me to work in these regions, and since I have been longing for many years to see you (in Rome), I plan to do so when I go to Spain . . . So after I have completed this task and have made sure that they have received this fruit, I will go to Spain and visit you on the way (Romans 15:23 - 24, 28, NIV).
Paul, in 63 A.D., wrote the books of 1Timothy and Titus. They were his twelfth and thirteenth writings in the Bible out of a total number of fourteen. His last writing was 2Timothy.

Jewish tradition regarding angels and their responsibilities assigns a rather interesting job to 63 of these spirits.
