The fourth longest book in the entirety of Scripture is Genesis with its 50 chapters.
Noah's Ark was 300 cubits long, 30 cubits high, and 50 cubits deep (Genesis 6:15).
The work of maintaining God's tabernacle in the wilderness was so laborious that only men who were between 30 and 50 years years old were allowed to serve (Numbers 4:1 - 3).
There was a penalty in ancient Israel if an unmarried man had sex with a virgin who was not engaged to be married. His penalty was to pay the woman's father 50 shekels of silver AND he had to marry her! Additionally, he was not allowed to 'put her away' or divorce her as long as she lived (Deuteronomy 22:28 - 29).
King David paid 50 shekels of silver to purchase the threshing floor where a death angel (brought by his own sins) was told to stop and not destroy Jerusalem (2Samuel 24). The location of the threshing floor became the place where Solomon built Jerusalem's temple (2Chronicles 3:1).
The gallows which Haman built for the use of having his enemy Mordecai executed upon was fifty cubits high (Esther 5:14, 7:9). Haman's plans, however, to kill Mordecai and have the Jewish people exterminated was thwarted. It was Haman himself who was hung on the gallows he had built!
How is the number 50 related to deliverance?
Fifty also symbolizes deliverance or freedom from a burden. God commanded ancient Israel that every 50th year, on the Day of Atonement, that a Jubilee was to be declared with the sound of a trumpet (Leviticus 25). During the Jubilee year ALL debts were settled in favor of the debtor and inheritances were returned to their rightful owners. Also, those who worked as slave laborers in order to repay a debt were granted their freedom to return home to their families and land.
