Meaning of Numbers: The Number 50
The number 50 derives its meaning from its relationship to the coming of God's Holy Spirit. Fifty can be found at least 154 times in the Bible.
After Jesus appeared to Mary Magdalene on Sunday morning, April 9 in 30 A.D., he ascended to the Father in heaven (John 20:17). His ascension, as a type of firstfruit from the dead (Revelation 1:5), occurred on the day God told the Israelites they were to wave a sheaf composed of the firstfruits of their harvest (Leviticus 23:9 - 11). It is on this day that the count of 50 days to the Feast of Pentecost begins.
In the New Testament, the word Pentecost comes from the Greek word for fiftieth (Strong's Concordance #G4005). Also known as the Feast of Weeks or Firstfruits, it was on this special Holy Day that God first poured his Holy Spirit upon about 120 believers who had gathered to keep the day (Acts 1:15, 2). They became the firstfruits of God's spiritual harvest of humans.
Jesus, as mankind's new High Priest in heaven, had to first offer the blood of his sacrifice (30 symbolizes this sacrifice) to God upon the heavenly atonement altar (which 20 represents) before the Holy Spirit could be available to all. This all adds up to 50, which points directly to the Feast of Pentecost.
Appearances of the Number Fifty
Of the five longest books in God's word, the book of Genesis has fifty chapters.
God promised Abraham that if he found only 50 righteous people in Sodom and Gomorrah he would not destroy both cities (Genesis 18:23 - 26).
Noah's Ark was 300 cubits long, 30 cubits high, and 50 cubits deep (Genesis 6:15).
The gallows which Haman built to use on his enemy Mordecai was fifty cubits high (Esther 5:14, 7:9). Haman's plans, however, to murder Mordecai and have the Jewish people exterminated was thwarted by Esther. Ironically, Haman himself hung from the gallows!
The Greek word glossa (Strong's Concordance #G1100) is recorded 50 times in the original Greek of the New Testament. It is found the most in 1Corinthians (21 times) followed by Revelation (8) and Acts (6). While the word can reference a human tongue (Mark 7:33, 35), it usually is used as a synonym in the Bible for a language or dialect used by a person.
And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues (glossa, 1Corinthians 12:28, KJV).
Number 50 and God's Temple
The work of maintaining God's tabernacle in the wilderness was so laborious that only men who were under 50 years old were allowed to serve (Num. 4:1 - 3).
The number 50 is woven into the details God gave to ancient Israel regarding the curtains, customs and size required for His tabernacle in the wilderness.
A set of ten curtains were commanded to be made (Exodus 26:1) with each one constructed from fine linen and colored blue, purple and scarlet with cherubim on them. Each curtain was to have fifty loops (verse 5) and have fifty taches (clasps or hooks) of gold used to connect the curtains together (verse 6).
A set of eleven other curtains, made of goat's hair (Exodus 26:7), were also to be crafted for the tabernacle. They, too, were to be made with fifty loops but the fifty clasps were to be of brass (verses 10 - 11).
The east and wide side of the tabernacle's rectangular court was to be fifty cubits wide. If we assume the cubit used was 18 inches (45.7 centimeters), this meant each side was roughly 75 feet (22.85 meters) in width (Exodus 27:12 - 13).
