The Meaning of Numbers: The Number 88
The possible meaning of the number 88 is derived from both facts about and writings within Scripture.
King Rehoboam, who ruled the Kingdom of Judah from 930 to 913 B.C., had 88 children (28 sons and 60 daughters)! He produced this offspring through 18 wives and 60 concubines (78 females, 2Chronicles 11:21).
The king's 88 children is the largest recorded royal family of any ruler over Israel or Judah. This is in stark contrast to his father Solomon who, although he had seven hundred wives and three hundred concubines (1Kings 11:1 - 3), is recorded to have produced only him and some daughters (1Kings 4:11, 15).
There are no chapters that have exactly 88 verses. In fact, only four chapters in the entirety of the King James translation have 80 or more verses. These chapters are Luke 1 (80), 1Chronicles 6 (81), Numbers 7 (89) and Psalm 119 (176).
Appearances of the number eighty-eight
Psalm 88 was written by priests who served during King David's reign (1010 to 970 B.C.). It encourages us to remain faithful and diligent, and to cry out to our heavenly Father all day and night if need be.
O Lord God of my salvation, I have cried day and night before You. Let my prayer come before You; bow down Your ear to my cry, for my soul is full of troubles, and my life draws near the grave (verses 1 - 3).
Single words and number 88
The phrase hapax legomenon, in Greek, means "thing once said." One interesting way of studying God's word is to look for hapax legomenon or words that are recorded only once in the Bible. There are several of these in the King James translation, one of which, "forgetfulness," is found only in Psalm 88.
Shall thy wonders be known in the dark? and thy righteousness in the land of forgetfulness? (verse 12 of Psalm 88).
Other words found only once in the KJV Old Testament include "reverend" (Psalms 111:9) and "eternity" (Isaiah 57:15). Single word occurrences in the New Testament include "grandmother" (2Timothy 1:5), "itching" (2Timothy 4:3), "wrestle" (Ephesians 6:12), "philosophy" (Colossians 2:8) and "fleshy" (2Corinthians 3:3).
Surprisingly, quite a few hapax legomenon are found in the book of Hebrews authored by the Apostle Paul. Some of these are "sundry" (Hebrews 1:1), "discerner" (4:12), "unskilful" (5:13), "forerunner" (6:20), "unchangeable" (7:24) and "finisher" (12:2).
